Bathrooms should be sacred places, but if you've ever been in a busy public restroom you know it feels anything but sacred. You feel rushed, and if you're using the stall you always fear that you'll make eye contact with someone through the crack in the door. This ceiling mirror takes those worries to a whole new level. Everyone has to keep their head down and stay chill, but unfortunately if it's your first time in the restroom you're going to instinctively look up. You just can't help it.
If I used the toilet here I'd be constantly looking up at it with a big grin on my face. Might as well own it, right? When in doubt, act like a total creep. That's my rule of thumb. It usually works out for me too.
