I'm traveling somewhere with my friend Mark. We're at a hotel, where we will be only very shortly, as if between flights. We were there before, and Mark has a key so we can get back to our room, but he tries it in the door and it doesn't work. Then he tries another door, and it doesn't work either. I'm not sure how to explain that, but he tells me that it actually isn't the key to our previous room, it's a random key that he found in a door when we were leaving, so he doesn't know which room it unlocks. He keeps going through the hotel trying to find the right door, but I'm pretty sure it's not one of the really nice ones in the middle. I think this project is silly, and we should just rent a room if we want one.
