#39 wins my vote for favorite post thus far.

Flat chested? Maybe change the clothes? Grow your hair out....?

perhaps the old man's wrinkles have shrouded his vision (if its not already bad enough) or maybe you had a cap/hood on? and there's nothing wrong with liking Twilight...but obsessing over the fictional characters is taking it too far. -A person who enjoyed reading the book.

Maybe he was senile and your parents played along as not to upset him.

You deserve it for being ugly.

Not a FML, not even close. Maybe if your parents forced you into an arranged marriage with him.

In middle school, I had a friend who had really short hair (she was a girl) and wore baggy jeans and t-shirts. One time, she was out with her parents and a waiter asked what their "son" would like to drink. After that, she grew out her hair, wore slightly tighter jeans, and more feminine t-shirts. And never again was she mistaken for a boy. Moral of the story? Relax, it's probably just because you don't dress in a feminine way or you have shirt hair. A few simple can change that.

#39 FTW.

I've been mistaken for a male also. Mainly because I had a pixie cut, wore sweatshirts a lot, and I have a boy's name (not a nickname, it's my real name). I haven't decided to become completely self-conscious about my body's look or started dressing like some loser woman from the fifties by wearing my hair in a ponytail, caking makeup on my face and wearing skirts like fat kids eat cake like these idiots have recommended. Please, just tell the old man you've been banging his husband for the past four weeks like nobody's business. There is no need to change yourself, all you have to do is clear up the situation with some classic offensive sarcasm.

Been there. It's always great when people mistake your gender, and even better when you have to correct them.
