My wife and I have a fairly common routine that helps us and apparently helps some neighbors also. We've been retired for about 12 years. About six years ago we relocated to a new 'subdivision' where we had all new neighbors to get to know. Most of them are still employed so are away most of the day.
We have for a number of years had a practice we refer to as 'merlot time'. It began as our time after work to sit, relax, share a glass of wine and talk. When we moved in here, our house was pretty stark and impersonal with little to encourage outdoor activities. The first things we did were to add a large rear deck and a large front patio. As we began our daily ritual, it did not take long before neighbors were regularly showing up after work to sit and visit with us.
Now I make regular trips out to get red and white wine, coke and beer by the case and various smoked sausage, crackers and cheeses to have on hand for these sessions. Folks out pushing strollers and walking their dogs feel free to bring along their contributions, stop in and sit a while. We are no longer strangers in the 'hood.
One of the best days of my IT career was the day I told my boss if the problem was so simple he should go fix it himself.
