Something I’d note is that the separation of “children” and “adults” is a pathology of current society. We sort of need it for a number of reasons, but one of those is that we routinely exploit adults, and a while back, the western world decided not to do that for children. This has caused a social disconnect between the hobbies of children and the hobbies of adults, but even in recent modernity, there was no such divide. I think it’s good to think of third places overall, rather than being “for” specific audiences. Everyone is part of society, so third places are for everyone.
