> People with kids sometimes experience this via all the activities they take their kids to

This is something welcome I didn’t expect to come from parenthood. Like many others I had thought to myself “how do you even make new friends in your thirties?!” and then once I had kids… bam. New friendship groups.

For us the local park and playground are a great equalizer in terms of economic stratification. But when the weather turns bad it rears its head again as people head to $50 a go trampoline parks and the like.

Public school is another unifier, of course. I’m in NYC and our preschool was very obviously not a reflection of the neighborhood or city around us. But once my kids entered the city-funded Pre-K they started to meet a ton of kids from different backgrounds. It’s very different from the childhood I had but I’m very glad my kids have it.

I kind of experienced that but the relationships were more superficial than I'd have liked. If the "shared interest" is happy kids together it doesn't directly translate to the adults shared interests. But then again, maybe it was just me being me.
