Varies person by person. Some I'm not particularly interested in, some seem satisfied with a head nod. I don't force it.

I do have neighbors I ask to water plants. Usually, I ask a neighbor if I can pay their 8-12 year old kid to do it. Lots of parents like the opportunity for their preteens to own some responsibility. I'm also among the neighbors that goes out after a snow to clear off walkways and cars for the elderly neighbors; that contact tells me which other neighbors are into the local community.

I've been in one super tight knit neighborhood where we did actual community things. Like I setup a little outdoor movie night in the common lawn and hosted a popcorn melodrama. I had the projector, audio, and movie. A couple other parents brought tons of popcorn. Everyone brought chairs and blankets to sit on. The kiddos had a riot eating it and throwing it at the villain on screen. That condo neighborhood is the gold standard I hold in my mind and compare all others I've lived in to.
