In an episode of the Iliad, Achaean warrior Diomedes meets Trojan warrior Glaucos on the battlefield, and for some reason, they start comparing their ancestry (ten years of battling the same people, you'd think it might have been a good idea to start trying to talk to them, but well). That's when they realise that Diomedes's grandfather welcomed Glaucos's grandfather in his home once, and as such, their families are bound by the laws of hospitality. They decide to be friends, swap their spears as a sign of recognition, and stop fighting for the rest of the war.
I went to my cousin's wedding last weekend. In the past fifteen years, I must have seen her twice at most, though both times with great pleasure (she's a lovely person with adorable children, so that helps). There, in Paris, I met with plenty of family members I had not seen for years, some I had met only once before in my life, some not at all. Yet all through the day, there was a permanent sense of recognition. Many people I spent the day with were virtually strangers, people I had last seen so long ago that I would never have recognised them if I had encountered them on the streets. But they didn't act like strangers. We spent a long evening talking about everything, introducing ourselves, catching up and saying over and over how happy everyone was to be here. And in truth, everyone was happy.
I suppose that this is what family has always been for. There are close relatives, the ones we see or ring when we can. And then there's a whole flock of cousins, great-aunts and all those people whose connection to you you'll give up explaining after half a minute of 'He's my cousin's husband's sister's fiancé -- wait a minute -- my cousin's husband's cousin's fiancé -- well, my cousin, of sorts, all right?'. Though you don't share your life with those people, you still share something. It's not a question of being close, or of knowing much about one another, because usually we don't. It's not a question of knowing if we actually like one another, because for a short while, there is something that makes us like one another anyway, and that thing is our knowledge of shared kinship. Being part of the same family means that every now and then, you have a great excuse to be kind and to be happy to spend time with complete strangers.
And whether or not we will meet again in the next twenty years, that's a beautiful thing to have.
