I was in my school and it was dark outside. The school had been emptied out for this "game", in which they put you in groups in a dark classroom and put bars of duct tape over the frames. Your job was to go out into the hallways to find the other teams so you could all escape, but you had to avoid the staff. If the staff saw you, you had to run and try to hide from them. The ultimate goal was to get outside without being caught. If you got caught, you'd be stuck in the building and denied permission to go home. If you escape, you're greeted by a teacher outside who sends you home.
