Girls, how cool is it that no one knows exactly what you're doing when you go in a toilet cubicle?

You can hear everything they do. You know when they are peeing, farting, if the toilet gets flushed a million times they are doing number twos, if you hear the sound of wrappers they are on their period.
I wish I was a guy when I go to an event and have to stand in a line for an hour when guys can just zip in and zip out.
