This putz wrote an acclaimed book that got turned into an acclaimed movie? I have to ask did the script writer or Ron Howard change a lot of dialogue and stuff to make it a normal movie? Maybe, he had a really good editor that was like, "Dude, this is some misogynist shit, take it out"
Now just here me out: What if the girls' bathroom is full up on people, or broken down for some reason. Wouldn't it be nice if a girl had to go into the boys' bathroom in an emergency, that they would have access to those things.
Boys don't have special requirements to use the bathroom. I can go anywhere just about. I can take leak on the side of the road with only a car door for privacy in ten seconds. Boom, I'm done.
