I'm traumatized

I spend most of my days at school and I drink a BUNCH of water. You know what that means...lots of trips to the ladies room. In nursing school there is an abundance of women and, when our class has a 5 minute break, this means a rush on the bathrooms. We have 4 floors and 2 sets of restrooms on each floor so I usually climb the stairs to avoid the mad rush. Today I decided to trudge about 500 ft down the hall to the set of restrooms on the same floor as my classroom. I walked in and thought, "Hmm...there are only 3 stalls in here. That's strange cause there are at least 5 down the hall." I went ahead and did my business, washed my hands (side note - you know you should sing Happy Birthday twice while you are washing your hands to make sure you wash them well enough) and started out of the restroom when I saw this --->
I had GONE in the men's bathroom. EWWWWW! While I am thankful that no man walked in or peed while I was in there, I am still immensely grossed out. And I wonder why the school has the women's room on the right at one end of the hall and on the left at the other end. The architect was on crack rock. Or maybe he was a man who wanted a woman to walk in on him while he was peeing. Either way I was mortified and am still half-giggling and half-retching inside when I think about it.
