The night of weird patterns

All my friends are firstborn. And I don't just mean close friends, but perhaps 10-15 friends/acquaintances, barring one or two exceptions. Most often of a pair of siblings (as it seems to be the favoured complement of offspring for most couples), but sometimes out of more than two.

My mother is the first of seven; my father is the second of five (and first boy). And I have a younger brother.

Woaw, holy crap, I'm not getting over this!

I'm reading the Coupland novel. I now want to make omelette for tomorrow's lunch.
