Gender Confusion?!?

So Emmalyn was upstairs this morning and I heard her in the bathroom. Not a big deal she's become very capable at going by herself but a moment later she says, "Mom I had an accident." I said, "What happened?" She said she didn't know and that she was just trying to pee standing up and it went everywhere. I started cracking up. How could I be mad at that? Anyway, I reminded her that only boys get to stand up at the toilet and girls have to sit down. She said, "Ooooohhhh." Too funny!!
