If it’s your son, I’d go with you need to take interest in them as a person. Idk I found it’s not too hard to relate to people. While we’re all very different, it’s often the same underlying things that are important to us. Plus, if you’re talking to a mildly intelligent person, you’ll often find it’s not too hard to keep a conversation going. Find out why they like it. What’s so special about that hobby. Learn something about it and broaden your horizon. Maybe there’s something to it. And it goes both ways… If they’re open to (new things) maybe they like to listen to you talking about woodworking. Or you can combine the hobbies and create something korean on the lathe (I’m making this up. But that should be possible with some topics, if you want to bond and spend some time together.)
