Noises Outside

There's a creak at the front door. It sounds like someone or something is outside. The dog hears everything. He jumps up and starts barking at the door. I go to the door to see if anything is there. Mostly expecting it to be nothing so I can get him to stop barking.

I look through the window in the door expecting to see a possum or a squirrel. As usual, there's nothing there. My mind's eye shows me an angry man with an ax. I'm relieved when the porch is empty.
