Someone is banging on my door in the middle of the night!
It's the middle of the night and someone is banging on my garage door!

That's quite scary!  Are you able to see who it is?
assistant
No, I can't see anything and I'm too scared to look out a window!

You might want to call 911 if they continue banging on the door.  Better safe than sorry!
