My younger son has been bugging me about skateboarding for a year. I’m not a big fan. I think it’s a roadmap to a concussion and also, what are we going to do about cello if he can’t play for six weeks because of a broken wrist?

But he was relentless, so I decided that if he’s so curious about something, I should say yes. He loved it, and also he loved the other kids at the skate park. Finally we found a group of kids for him. It’s too bad that they can’t skate until after school, but he practices a lot while they are in school.

My older son saw how well things were working out for my younger son, so he wanted to do it, too. I was surprised. He has lousy balance and also a big part of skateboarding is knowing where the other kids are and what they are likely to do next so you don’t run into each other. This is very very hard for a kid with Asperger’s. But I told myself that things that are hard for him are good for him.

I told him he had to take five lessons before I’d buy him the $200 skateboard and $50 skate shoes and $40 helmet. And then the week after we bought all that stuff, he announced that he doesn’t like skateboarding any more.

My first thought was: “Great, because the only kids who were crashing into each other at the skatepark were my two sons, with intent to harm, so I’d just as soon get out of there.”

But then I thought how it’s not good to let him stop just as it gets difficult. And I already spent a lot of money.

Then I thought I should let him direct his own learning. I don’t want him to be the type who stays in a job that he hates. So maybe what he’s learning is how to quit.
