That's more profound than you think, David. I'm in my **ehem** 40's and my mom & dad are in their 70's and 80's respectively......and I STILL have to fall back on that maxim.
The first time I show up with a chromedome, my mom will probably flip and my dad will probably just snort in disgust.
He didn't know what to make of it. They still see me as the little guy in 1966
At least I've finally grown into my ears!!!
Look at this way - you warmed them up by getting the tattoo!! I'm in the same boat as you with Mom, Dad and the Grandmother
