Hmm...I'm not really sure. I know a lot of girls like to gopssip in the bathrooms without guys. O_o
If you're in a public place at night, I can understand why some girls would go in pairs, just in case something
happens.
Quote by joycevMy best guess is just so we arent alone. Most girls never want to be alone in any situation, so bringing a freind would not only make things safer if something were to happen but then you have someone to talk to also.
I think that's the main reason. When I go to the bathroom, I usually turn to my friend and ask "You coming?", without ever wonderig why. ^_^'
