Do you use the restroom in front of eachother and take turns? Are you doing makeup? Deciphering texts from crushes?
I find it a little odd yet fascinating. It’s different for guys. Me personally, I wouldn’t be that comfortable having a guy friend in the stall with me while I was using the restroom. It would feel really weird.
At my work there is a single stalled restroom for women, meaning there’s only one toilet. I see women go in together often. Not with children or anything because that makes sense. But like teens and young women.
