We tried to introduce ourselves to our neighbor's on the other side of our next door neighbor. They have a cool mule drawn, covered wagon, that they drive down our road sometimes. One day, the lady was going by, in the wagon, with her father (I'm guessing). We saw them coming and went out to the end of the driveway, to introduce ourselves. I said "Hi" as she got close. She nodded her head (in acknowledgement) and kept right on going. She almost ran my toes over, we were that close! We were shocked!

She's driven the wagon by since, but we don't bother going out to the road anymore.
Our only other neighbor's 1/2 mile away) just moved in last Spring. When The kitty, Buttercup, started hanging out here, we took him down to see if he belonged to them. They are young with children. They seemed nice enough, but we never see them, and they aren't home much. We invited them to come down anytime, so the kids can see the goats and ducks, but they never have.
Down the road further is the couple that owns the 160 acres across from us, that a dairy farmer leases to run his heifers on. We know them, but they aren't very friendly, except to say "Hi" and go on their way. Other than that, we don't have any neighbor's that we could socialize with.
We have our church friends, so we have plenty of socialization. They are a really nice group of people.

Besides, we have a fellowship meal every 2nd Sunday, and get to have a party, of sorts once a month, with our friends. So, our situation is different, from your, but the same.
