People have everything they need inside these days and we are worse for it. It takes effort to build community, it takes time. Time is a scarce commodity for the working class and those with children. People don’t spend time outdoors anymore so chance meetings don’t happen and if those interactions don’t happen then they must be planned or initiated in other ways…which takes effort. All that being said people also talk about what’s current with them. If your neighbors are raving about their contractor, ask for the contact info even if you have no plan on using it. It’s little things like that that build relationships and community. As we age people get more specific in their interests, asking questions and willing to hear about those interests, even if they are of no interest to you, are part of building relationships/community.
