The last time you walked down the street in your neighborhood, to how many people did you greet? Sure, it’s hard if you don’t live in a residential area. If you are passing 50 people on street in a big city, it’s kind of impossible to say hello to everyone, unless you’re like Buddy in the movie Elf.
But if you encounter just a couple of people on the street, is it so hard to say a simple hello? It’s not that I think that you need to talk to everyone, but when you pass by someone and he or she is not engaged in conversation, it seems strange that you wouldn’t acknowledge another human being, if not out of kindness, at least out of respect. Isn’t that what manners essentially are, a show of respect for other human beings?
