My ace in the hole as a human being used to be my capacity for remembering birthdays. I worked at it. Whenever I made a new friend I made a point of finding out his or her birthday early on and I would record it in my Filofax calendar.
I'll never forget my 24th birthday when my tooth got punched out. And for a second I was like it would be really hilarious if I sold it on eBay. But I can't that's just too creepy. I don't think I can go there.
