What makes a good neighbor?

The world is a different place, when I was a kid it was a front porch community now the front of most homes is a garage. People come home go in through garage close the door and hide in their house. I know my neighbor, next door, but we are not friends, we are cordial and friendly but that is the extent of it. My old neighborhood we were friends because of having children the same age and in school together but sadly when you move into an established neighborhood and there isn’t a child connection cordial is usually the way it goes.
