The last time I stopped to help a total stranger was yesterday, in a restaurant. Being a senior citizen, I don't stop to help anybody on the side of the road or any other place where I might be putting myself in danger. I stop to help people, for example, who have dropped something in the grocery store aisle or who can't reach something on a shelf.
These days, I prefer doing anonymous 'random acts of kindness'. They are just between me and God as I understand God, and I don't need any human recognition. Some of them are quite fun.
