After a quiet day spent mostly in contemplation, you go to one of your favorite restaurants where you have a leisurely, delicious meal. The food – not always the kind you’re in the mood for – tonight hits the spot, the company is charming. Once you’ve finished eating, you sip your drink, chatting with your dinner companion. Finally, deciding it’s time to start heading home, you excuse yourself and retire to the restroom.

Inside you make the necessary adjustments to your clothing and sit down. You look around, peacefully, and then you see this:

Automatically your eyes jump to the drain, located in the center of the room, only a foot from the toilet. All at once you notice that the floor is a bit sticky and, worse, you are standing on the bottoms of your pant legs.
