On one very cold night, a rich man met a homeless old man outside. The millionaire stopped and asked him: “I see you don’t have a winter coat, you’re not cold”? The old man looked at him for a long time and then replied: “I don’t, but I’m used to it.”
The rich man, astonished by the answer he received, said to him: “Wait for me! I’m going into my house now and I’m going to bring you a thick coat to keep you warm at night.
