I have no problem with socialization and I have an unusually-active social life for a thirty-eight year old married man with three kids, so I clearly don't lack initiative.

With that being said, all of my neighbors are either elderly, shut-ins, or just don't want to be bothered; even the ones with kids.

My wife & I helped organize a Block Party last year and I'm fairly certain it resulted in 0 new friendships for any of the attendees.

What's the solution here? Friendships need to have mutual interest, no?

I think it's a circular problem. Like, my kids don't go outside much because there are no other kids outside to play with.
