Even a simple word “Hi” makes another man smile back at you. A conversation is then created, and many other good things follows. We don’t want to live in a world of strangers*, especially in your neighbourhood, your workplace, sometime this people you know can come to your assistance in time when you need it.
*we travel some distant to find a friend, and the people next to us are “not your friends, you see them every day”. I smile to almost anybody, sometimes my wife think I am crazy, honestly, I feel so good inside. I get the return smile always. I wish there is no barrier between people, just love.
We need people as the people need us.
