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.
Do you know the most important trait a man can have? It is not executive ability; it is not a great mentality; it is not kindliness, nor courage, nor a sense of humor, though each of these is of tremendous importance. In my opinion, it is the ability to make friends, which, boiled down, means the ability to see the best in man.
