Most embarrassing memory? Now what kind of question is that to ask, really? I wonder how many people actually answered this one.
Will I answer it? My idea of embarrassment I guess is weird. Clumsy? I know I can be. I'm not easily embarrassed by that sort of thing. I'm not easily embarrassed by the things I enjoy that many people may find geeky. I have no 'guilty pleasures'. Guilt should play no part in pleasure.
My point being, if something is really all that embarrassing, why post it on LJ for all the world to see?
