I volunteer once a week at a local charity shop. It is sometimes a strange world to move around in. Strange is probably the wrong word, but it is a new sub-culture of sorts. Most of my fellow volunteers are older than I am, though I am no spring chicken. They are nearly all women, and I have for the last 30 years worked in a male dominated world.
My fellow workers come from all walks of life, as do our customers. We have our "regulars", people who drop by every few days to see what new products we've brought out for sale.
Not only does the store have it's regulars, we, the volunteers, have our personal regulars. Inadvertently and over time, the customers find out who is working when. Now, not a shift goes by when my regulars drop by to browse around, but also to exchange a bit of small talk. Each encounter is a small doses of happiness.
