I am fairly tall so I walk into a lot of low-hanging stuff. People open the bay door enough to walk out. The door is now open to my chest.
My Mom put up all the mirrors in our house, back in Maryland. The tallest one and I can see the bottom of my chin.
The basement is the land of ducking and bonking. The day I became too tall to walk in the basement, was a memorable one. I ran down the slippery, uncarpeted, wooden stairs, taking them three at a time (because I am a boy!) and when I got to the bottom, continued running, right into blissful unconsciousness. Scalped myself on the lintel, above the next doorway, which was about 6' high. I am 6'2". Many a first word, upon regaining consciousness is "Owwwwww."
Dad saw me coming through the doorway, feet first.
