Why are people so weird.??

Are they like this with each other in just this country or is this just a human thing??

I have tried to be friendly to 2 neighbors, but they dont want to be friendly at all.
I baked cookies one Christmas and distributed them in the neighborhood; to about 10 people.

Are these people just so caught up in their nasty lives of debt, possibly a bad marriage and or a bad job they dont want to be friendly??

I wish I could move into the country and not have neighbors but right now cant afford this.
