This girl (who is now infact, my girlfriend) liked me for a while before I ever caught on. All of my friends knew, just not me. I guess she tried to hint at it for a while, but as a guy, I really didn't notice:

We don't get hints. We're less sensitive to subtlety than rocks. Sorry girls, if you want us to notice something, spell it out for us.

But on a semi-related note, I do have a wonderful girlfriend, who accepts me even though I am a giant nerd. And she even reads my blog. <3
