Peeing in fear

At work, I'm in the washroom, peeing, and then I realize I don't completely remember the walk to the washroom.  I zone out or go on desk-to-toilet autopilot or something.  And then my mind panics slightly. 

I am in the women's washroom... right??! 
No no, I am... I didn't see any urinals. 
And there's the napkin/tampon disposal. 
I'm where I should be. 
Phew.
Continue peeing.

It's sad how often this happens.
