“Actions speak louder than words, and a smile says,“I like you. You make me happy. I am glad to see you.” That is why dogs make such a hit. They are so glad to see us that they almost jump out of their skins. So, naturally, we are glad to see them. An insincere grin? No,that doesn’t fool anybody. We know it is mechanical and we resent it. I am talking about a real smile, a heartwarming smile, a smile that comes from within, the kind of smile that will bring good price in the market”-D.Carnegie
