Knowing your neighbors

I have a condo and have lived here for almost 23 years, but we all pretty much keep to ourselves. I say hello when I see my neighbors, but nobody is overly friendly and we don’t socialize together. So I don’t really know any of my neighbors or say more than a few words to them. It's also the kind of place where very few people stay a long time. Units are constantly being bought and sold, and some are occupied by renters who don't stay very long. Part of the problem is there is no common area where we can hang out and just talk to each other. There is no rec room or pool. There's a laundry room, but it's small and nobody even sticks around to watch their laundry. We just go back to our own units and wait until the laundry is done.
