As you walk around, doing your job of cleaning you come across a really dark room and notice a face--when you turn on the light they quickly hide their face from the light. "AGHHH, TOO BRIGHT!" When you turn off the light again he seems to go back to being fine, and he notices you in the dark. "Oh! Hiii!" He seemed to wave at you but it was hard to see. Do you try waving back? Say something? Turn on the light? Or ignore them?
