I can’t speak for anyone else but me, but I always enjoy the hobbies my boys take up. My boys are in their learning to program phase, and of course being a programmer myself, I couldn’t be happier. But I’m just as content discussing (mostly listening to) whatever they’re doing in Roblox on any given day.
My dad did his absolute best to try to relate to me. I was weird, didn't get into sports, played a lot of video games, and have been in and out of bands since I was 15 or 16. He came and watched us practice out in the shed (when we were fucking awful) and bought video games he thought I'd like (he was very wrong, but I loved them anyway).
These days we play an online game together a few times a month and trade barbecue recipes. We've even sent each other our dry rubs for brisket and ribs. I'm a middle aged dude and that guy is my fucking rock.
Keep being there for your boys and in 30 years they'll talk about you like you're the best person they know. I wouldn't trade my dad for anything in this world. I don't always agree with him, but he's still one of the best people that have ever existed.
