My grandmother told me that recently, she went with her sister to a store. Her sister just had to run in, so my grandma decided to wait in the car with the windows rolled down for air, since it was a warm day. A stranger passed by and saw her sitting in the car and was concerned about her welfare. This stranger stopped and offered my grandma some water and asked if she needed anything else. We all thought it was very sweet of a stranger to stop and make sure she was ok.
