I hate co-ed bathrooms.  It makes me feel like a prude saying it, but it’s the truth.  Boys should go to the little boys room and girls should go to the little girls room.  That way we can avoid situations such as me walking out of the restroom, seeing the next person in line is the guy I’ve been eye-flirting with all night, having to say, “Um, the flush doesn’t seem to be working all that well.  But, it’s only pee, so no big deal,” and then being unable to make eye contact with him for the rest of the night knowing that he’s peed on top of my pee.
