The new "common" names, according to a kid

My son and I were waiting for his swim lesson to start when I asked him to remind me of his teacher's name.

"I can't remember, mom." he said. "But it's something common."

"Sarah? Jessica?" ( The teacher in question is probably in her mid twenties so I was probably already off by guessing the common names of my childhood.)

"No, those aren't common names!"

He then told me that common names for girls are Mae and Charlotte.

For boys they are Chris,  ( this is because 80% of the kids we know have a dad named Chris, no joke), Henry and Max.

I never did figure out what the teacher's name is....
