You are alone. It's 3 am. Loud thunk right outside your bedroom window. Do you pull up the sheets and hope it was nothing or grab the ball bat and head outside in your skivvies?
My "bat" happens to be a Springfield...
I wife's best friend once called me in the middle of the night because she heard a sound in the middle of the night. Too terrified to sleep.
Half hour later I find a window open and a raccoon eating from her garbage can in the kitchen. Lots of fun
Wake up my husband, if he's not home - call the neighbor
I look out the window, see that it's a cat, & go back to sleep. (Happened recently, although it was 2 AM... my windows are at ground level so I was looking right at the cat.)
If I'm alone, I'm more likely to huddle up. If not, I'm more likely to look.
You picked the wrong house, buddy..*evil laughter*
