My phone doesn’t ring for days at a time, yet when I am sleeping in, or sleeping one off, on a Saturday morning, some goof will call.
Rarely does anyone call at my door, yet when I am in the shower, sitting on the toilet, or shaving while naked, someone will knock like a manic at my front door. Later, when I can go to the door, there will be no sign that anyone was there. I might just have to install a camera.
Sometimes both will happen at the same time.
