The problem with LJ: we all think we are so close, but really we know nothing about each other. So I want you to ask me something you think you should know about me. Something that should be obvious, but you have no idea about. Ask away.
Then post this in your LJ and find out what people don't know about you.
A couple of caveats, I've seen elsewhere: (A) it doesn't have to be just one question. (B) I reserve the right to refuse to answer, but I'll try to explain why I think that way.
