I tell you what kind of annoys me. Guys wearing caps or hats indoors. Especially in restaurants.
I admit I may sound like an urbanite railing against the uncouth ways of my redneck neighbors but...
My father grew up on a farm and was the last in a long line of generations in my family who farmed. My dad, my grandfather, my mom, my grandmother, Bum Phillips... they all taught me. Men should not wear their hats indoors.
