We are lucky to live in a pleasant neighbourhood, I know most of my close neighbours and give art lessons to the lady across the street. We chat with most of them from time to time and will let them know if they left their car lights on or if we are having people over. Mind you it is a rural community and the local shop keepers recognise you and pass the time of day with you seeing the same people day after day builds a sense of community.
My parents live in a wealthier street and they have little or nothing to do with their neighbours.
