[usr] It's the middle of the night and someone is banging on my garage door! [sys] That's quite scary!  Are you able to see who it is? [usr] No, I can't see anything and I'm too scared to look out a window! [qst] [None] [bhv] I'm in a negative mood, please comfort me.
You might want to call 911 if they continue banging on the door.  Better safe than sorry!
