Like @Pachy I’m not unfriendly, just private, alone, and either at work, inside the house, or mowing the lawn / shoveling the driveway or grilling my dinner. So I don’t spend a lot of time outside (and when I do, my back yard is surrounded by brush, making my yard nearly invisible. (In the winter time when the leaves are all down, I can walk into my back yard and count 17 rooftops and houses to go with ‘em. In the summer time when everything leafs out, I have to peek around some to see my three closest neighbors, and I can’t see all of them at once from any part of the yard.)
But since I’ve lived here for 14 years now, and some of my neighbors have been here even longer than I, I have met most of them, and we’re at least casually friendly. To my north is a gentleman of approximately my own age from Barbados, his girlfriend and occasional family members. We occasionally help each other out with snow removal. Lately I’ve helped him more than the reverse, since his snowblower was stolen several years ago. When I get out my snowblower for snow that’s too deep or heavy to shovel, then I do his driveway and sidewalk, too. On mornings with light snow I’ll often find that he has already shoveled the sidewalk in front of my house. On the worst days of winter as I’m clearing his driveway and he’s clearing the edges, I kid him about why he ever left Barbados. He just shakes his head and smiles. Two years ago after a particularly bad storm he gave me a bottle of Barbadan rum.
To my south is a small townhouse development that is pretty well screened from my house (plus my garage is on that side of the house), so I normally only see them when they’re out on the front deck grilling something delicious, and I tell them so. But that’s really our only interaction.
There are three families across the street, two couples with young children and one couple with no kids. I’m on a nodding-and-waving basis with each of them. A couple of years ago during a heavy snow I cleared both of their driveways and walks, too, because they were away when it was worst, so they were able to come home to a cleared drive. Since then the favor has been returned. That’s one of the nicest ways I’ve seen on a routine basis to say “Welcome home, neighbor.” I’ll definitely have to keep that up.
Other than that, I’ve returned a lot of mail around the neighborhood to rightful addressees. I think the Postal Service must be hiring the blind, sometimes. And I just got back inside from clearing the immediate neighborhood of the various trash items that find their way to this low point in the road after a rain.
I would rather be “the neighbor everyone likes” – without bending over unnecessarily for that – than feel like I have to like everyone. But it seems that the more likeable I am, the more I like them, too.
I’ve also lived at times in neighborhoods like @DrasticDreamer,‘s so I can certainly sympathize.
