How to find a kid with the same hobbies?

Cool hobbies!

I tried a website for pen pals a while back, looking for friends for my son, and never heard a peep out of them.

I’d recommend looking locally. I don’t know where you’re located, but here in the US there’s a popular website called Meetup, where people can post their clubs online to find new members. Maybe there’s something like that where you live?

It might be cool to look up, say, a robotics club. Something active that you can take part in with other kids.

Try Facebook, almost every club will have a Facebook page promoting their activities.
