So, I just spent five minutes knocking on my neighbor's door. Just knocking. Waiting. Hearing them moving around inside. Then knocking again. Listening to their dog bark. Waiting. Then knocking.
Finally he swung open the door and looked like he was ready to punch me.
"Excuse me, you left your keys in the door."
"Oh. Alright then."
When he closed the door, do you know how tempted I was to knock before I ran away?
