Lift.

You're waiting for the elevator. It arrives. People wander out. But not all the way out. Just out enough to keep you from entering, just out enough to keep the doors from closing.
Then they stand there like lost sheep while realising this isn't the floor they want.
Then they stand there s'more.
And then they look at me.
"Are you going down?"
No, fuckwit, I'm going UP, hence why I hit the UP button and why your car, which is also going UP, STOPPED HERE!
