How old are you? That question is so innocuous, but so loaded. I am always amused at the idea that as you are a certain age, you need to be/do/like/say certain things.
I am interested in things that would belie my age.
I know about Babbit bearings and zirc fittings on old Chevy trucks, and have helped repair a Studebaker. I know some about donkey engines in logging. I also know some about making stone and bone arrowheads. Does that make me a certain age? I also like (some) rap and hip-hop, think skateboarding and motorcycles are sweet, and I knit. Does that change the opinion of how old you think I am?
I have found that people think you are as old as you let them think you are. A friend of mine had been in Viet Nam, and a news article had come up about Jane Fonda. He was, to put it mildly, outraged... I was puzzled. She had never been on my radar, and so I asked why he was upset. After hearing probably more than I will ever remember about 'Hanoi Jane', he then snorted, "You should know this, you were around then!"
I looked him squarely in the eye, and said, "Just how old do you think I am?" He responded that I was his age. I asked him what he was doing during the Moon Landing in '69. He told me he was in the Marines. I told him I was a toddler, sitting on my grandparents table, watching the landing. Also, according to my parents, I was much more interested in my Oreo cookie dismemberment. He looked stunned. "But you act so much OLDER!"
So. Act your age? Meh. Act how old you WANT to be. That keeps 'em guessing!
