We were watching a movie in a cinema. After the movie we wanted to secretly enter another room so we could see another movie.
We sneaked around, but all other rooms were closed already. When we tried to get to go back to 'our room' to go to the exit, there was a guard standing there, waiting for everyone to come out.
He left and we carefully walked towards our room, when we saw the guard standing by the exit! He would know what we were doing, so we hid instead.
Then... the lights went out! We walked towards the front and saw an employee walk towards the exit. We couldn't just run to her and say we were left behind... so we stayed and she locked the door!
We tried to open the door, but it wouldn't open. There was only one thing to do... we stayed there for the night. The next day we mingled with the crowd and nobody ever found out!
