Believe in angels. They still exist. Take Ralph Davis and Rose Preston for example. I rode around the streets of South Providence with them and recorded their many good deeds. Every Saturday morning and every Wednesday evening in summer or winter, in rain or snow or 100 degrees, they are out there looking for folks in need. They offer a sandwich, or a pastry, a hot chocolate, or maybe a pair of fresh socks or warm gloves, even a little hope and human kindness. They have been on the streets for many years, helping the homeless without judgment or discrimination, just trying to do some good. So believe in angels. Here are two, right under our noses.
