Someday...

We were out to dinner the other night, and when I took Jude to the restroom, he asked me why girls have to sit down to go. I told him it's because we don't have penises. He then looked at me sympathetically and said, "But someday you will..." I informed him that girls do not, in fact, grow penises, and he again assured me, "Someday."
I tried to explain that we just have different body parts and he asked me if he had always been a boy. I said, "Yes, and someday you'll be a man," to which he excitedly replied, "YES! I love being a man!"
