Okay, to all of you who don't know it, it's creepy to talk to people in a public restroom, no matter how well you know them. A public restroom is not a social setting!
K, here's what brought this to my attention. I'm at work. I went into the restroom to use the restroom, not to socialize. One of the other ladies from work was in there, and she started talking to me. How awkward & uncomfortable it is to try to pee when someone else is trying to carry on a conversation with you. I didn't interrupt her peeing with conversation. Why did she think it was okay to interrupt mine?
