I See The Light

I got up at 4:45 a.m. this morning to use the bathroom.  Joe was fast asleep in the bed with me.  As I walked to the bathroom, I noticed that all the lights were on in the living room and the kitchen.  I don't know why - they weren't that way when I went to bed.  As I went to turn them off, I noticed the front door - standing wide opened where anyone could have opened up the screen door and walked right in.
