A cool memelicious thing about you, not me

I got this from my sister-un-law, trueheart:

I know little about some of the people on my friends list. Some people I know relatively well. I've read your user info, or we have something else in common. Some of you I know a little and look forward to getting to know over time.

I'd love it if every single person on my friends list would volunteer a personal nugget of information that might be evidence of a defining trait. Yes, even those people who think I know them reasonably well. Then post this in your own journal if you like.
