I am regularly offended by people's behavior in the restrooms here at work, and it occurs to me that perhaps (and I'll give them the benefit of the doubt) they are entirely ignorant of the psychological havoc they wreak. Allow me to elucidate.
The courtesy flush
I know that in civilized society, we like to avoid unnecessary contact with our own crap. But I assure you, you will have far fewer dealings with it if you flush thoroughly. And if one flush doesn't get the job done, it's not an admission of weakness to give it a second go-round. I know a few men who might consider it a source of pride.
It is okay to recognize and greet someone washing her hands at the sink as you enter the restroom. It is not okay to peer through the cracks of the stall door to see if someone you know is sitting with her pants around her knees. Honestly, I thought that was common knowledge.
Some people may think that all grunting, heavy breathing, sneezing, and humming sound the same as anyone else's. Not true. And that's a picture of you in my head that I don't want to carry around all day.
I don't know about you, but I've been using the big-girl potty all by myself for a good twenty-six years. I've become quite skilled at having successful bowel movements. Applause is not necessary. (Again, honestly!)
And finally, please consider the following topics off-limits for stall-to-stall conversation:
I understand that men have their own rules about restroom behavior, and gentlemen, I applaud you. But certainly not when you're least expecting it.
