There are two bathrooms in my apartment – one off the main living room, and the other connected to the sink area in front of the shower. My roommates hardly ever use it, so it always sits in the back of our apartment unloved (except by my hairy ass). There is a funny little sign right above the handle:
So the correct answer was in the bathroom. Several people came up with the right location for the sign, but the winner this week is Akaki. He was the only one who came up with the correct derivation of the phrase – I misread a て as the question mark and the Japanese period as the question mark’s little dot. Nice work! I owe you a beer, Akaki!
