I was just reminded of yet another set of awkward gender related compliments...
Over the summer a girl I was friends with from class would often feel it her duty to let me know what she really thinks of me... it often went like this (I don't think my replies are necessary).
Girl: I totally just checked you out. Sorry.
Girl: I hope it doesn't weird you out that I stare at you during class.
or, my personal favorite...
Girl: If you were a boy, I would totally date you. I told them (the class) that the other day. But I just wanted to let you know that if you were a boy, I'd date you.
