A bit apprehensive (another meme)

I got this from bluestocking79, who has answered some very fascinating questions in a most articulate manner, in spite of having the flu! Here is the meme - I've seen it before, but never dared to do it:

The problem with LJ: we all think we are so close, but really, we know nothing about each other. So ask me something you want to 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.
