Cliquebusting

Last evening we hosted a party at home. Like all parties we host, we used Graph Theory to plan this one. This time, however, we used graph theory in a very different way to how we normally use it – our intent was to avoid large cliques. And, looking back, I think it worked.

First, some back story. For some 3-4 months now we’ve been planning to have a party at home. There has been no real occasion accompanying it – we’ve just wanted to have a party for the heck of it, and to meet a few people.

The moment we started planning, my wife declared “you are the relatively more extrovert among the two of us, so organising this is your responsibility”. I duly put NED. She even wrote a newsletter about it.

The gamechanger was this podcast episode I listened to last month.

The episode, like a lot of podcast episodes, is related to this book that the guest has written. Something went off in my head as I listened to this episode on my way to work one day.

The biggest “bingo” moment was that this was going to be a strictly 2-hour party (well, we did 2.5 hours last night). In other words, “limited liability”!!

One of my biggest issues about having parties at my house is that sometimes guests tend to linger on, and there is no “defined end time”. For someone with limited social skills, this can be far more important than you think.

The next bingo was that this would be a “cocktail” party (meaning, no main course food). Again that massively brought down the cost of hosting – no planning menus, no messy food that would make the floor dirty, no hassles of cleaning up, and (most importantly) you could stick to your 2 / 2.5 hour limit without any “blockers”.

Listen to the whole episode. There are other tips and tricks, some of which I had internalised ahead of yesterday’s party. And then came the matter of the guest list.

I’ve always used graph theory (coincidentally my favourite subject from my undergrad) while planning parties. Typical use cases have been to ensure that the graph is connected (everyone knows at least one other person) and that there are no “cut vertices” (you don’t want the graph to get disconnected if one person doesn’t turn up).

This time we used it in another way – we wanted the graph to be connected but not too connected! The idea was that if there are small groups of guests who know each other too well, then they will spend the entirety of the party hanging out with each other, and not add value to the rest of the group.

Related to this was the fact that we had pre-decided that this party is not going to be a one-off, and we will host regularly. This made it easier to leave out people – we could always invite them the next time. Again, it is important that the party was “occasion-less” – if it is a birthday party or graduation party or wedding party or some such, people might feel offended that you left them out. Here, because we know we are going to do this regularly, we know “everyone’s number will come sometime”.

I remember the day we make the guest list. “If we invite X and Y, we cannot invite Z since she knows both X and Y too well”. “OK let’s leave out Z then”. “Take this guy’s name off the list, else there will be too many people from this hostel”. “I’ve met these two together several times, so we can call exactly one of them”. And so on.

With the benefit of hindsight, it went well. Everyone who said they will turn up turned up. There were fourteen adults (including us), which meant that there were at least three groups of conversation at any point in time – the “anti two pizza rule” I’ve written about. So a lot of people spoke to a lot of other people, and it was easy to move across groups.

I had promised to serve wine and kODbaLe, and kept it – kODbaLe is a fantastic party food in that it is large enough that you don’t eat too many in the course of an evening, and it doesn’t mess up your fingers. So no need of plates, and very little use of tissues. The wine was served in paper cups.

I wasn’t very good at keeping up timelines – maybe I drank too much wine. The party was supposed to end at 7:30, but it was 7:45 when I banged a spoon on a plate to get everyone’s attention and inform them that the party was over. In another ten minutes, everyone had left.

Ganesha, wine and vodka

I know the wife has been intending to blog about this for a while now, but in this big bad blogosphere, intent counts for nothing, and given that she hasn’t written so far, I should go ahead and write this blog post. The basic funda is that Ganesha idols in “traditional” Indian culture, wine in European culture and smirnoff plain vodka in “modren” (sic) Indian culture are all similar.

So two days back I got invited to a “bring your own liquor” party. Now, there were other attendees who mentioned they were bringing stuff that I knew I was interested in drinking, like Desmondji Agave and Amrut Two Indies Rum. From that perspective, I knew that I wouldn’t be drinking whatever I carried. Yet, not carrying anything would make me look like a cheap guy, and this is one circle where I want to preserve my reputation. So what did I do? I picked up a bottle of Smirnoff plain vodka, simply because it is the most “fungible” drink. I’ll explain later.

Similarly, when you go for a function in India and don’t know what to gift, and are “too traditional” to gift gift cards, and think it’s not appropriate to give cash, you give a Ganesha idol. So for example after our wedding we had tonnes of Ganesha idols at home (similarly after our housewarming last year). Why did people gift Ganeshas? Because it is the most “fungible”. Again I’ll expect later.

And the wife reliably informs me that in Spain, when you have to go for a party but don’t know what to take, you take a bottle of wine. I don’t know about the fungibility of wine, but the fact that it is universally drunk, can be shared widely and is seen as a classy symbol makes it a popular choice of gift. So what connects these three?

So what connects? Fungibility of course. Economists have long argued that the best gift is cash, for the recipient can utilise that cash to buy the item that gives her maximum utility. Any non-cash gift decreases utility from the maximum that can be achieved by giving cash. This is a different discussion and I’ll not touch upon that now.

When you are going to a party, you can’t take along cash, so since the top choice is not available you take the “second best” option. What is the “second best” option in this case? Something that is close to cash, or something whose general utility is so high that the recipient values it as much as she would value the equivalent amount of cash. Of course you don’t assume that the recipient will sell your gift for cash, so you gift something that is a “safe option”, that you think they will have the least chance of rejecting.

So why did I take vodka? It is a universally popular, colourless odourless tasteless liquid, and I estimated that there was a good probability that the demand for that is going to be high. So even if I don’t drink what I carried, I posited, someone else will, and that will help me deliver maximal utility to the party.

With wine in Spain, you know everyone drinks and appreciates it, and there is a chance that it might be opened at the party itself. Even if it isn’t, wine in a sealed bottle doesn’t “depreciate”, and the host can then pass on some of the unused bottles at a party  that she attends! And soon there will be the virtuous wine circle. So essentially wine doesn’t disappoint, and is put to good use.

And it is exactly the same story with Ganesha idols. Like wine, it has intrinsic value. Who doesn’t like idols of a cute elephant-headed God? Maybe people who already have too many such idols? But then Ganesha idols don’t depreciate either, so all you need to do is to keep it in a safe place and pull it out the next time you’re going to a function! And thus the virtuous circle of Ganeshas will continue!

As it happened, at the end of Tuesday’s party, the bottles of Desmondji and Amrut Two Indies were empty. The Smirnoff I took remained unopened, as did another similar bottle which was possibly brought by another safe player. But I’m not concerned. I’m sure the hosts will consume it in due course, and even if they don’t, it will come of good use when they go to a party next!
