My teenager is an alien

I'm in the kitchen cooking a normal dinner on a normal weeknight
after a normal day at work and I hear my teen-age stepson, 15,
ask his dad "So what do you think about me getting a tongue ring?"
What! Is this what teenagers are thinking about and wanting to do?
His dad told him "No" in lots of ways, and Rich replied with
"But why not? Piercings aren't wrong. You aren't saying piercings
are wrong now are you?"
Of course, no explanation we provided was acceptable,
so he had to settle for..
"sometimes it's our job to save you from yourself!"
