Is it normal to turn the doorknob while shutting the door behind you?
I have a couple in-laws living with me and my wife and the way they shut doors behind them drives me nuts. I was taught to not let the door slam shut behind me by keeping the knob turned while closing the door. The way these people walk through the house swinging doors shut behind them, letting the doors slam into the door frame, is enough to make me want to twist some heads off. Is this normal?
