One day, after a long walk with his owner, a dog lay down on the floor to rest.
One of his master’s friend passed by to pay a visit and they started to chat. The dog from time to time made some noises and the friend asked the master if the dog was fine. The master answered not to worry about the dog, everything was fine with him.
They continued to talk but the dog did not stop complaining. The friend asked again if the dog was really okay. The master replied that the dog was fine, he was just lazy. Actually, the dog was trying to sleep but he was lying down on a nail. The dog was so lazy to be ready to sleep on a nail, even though it was very uncomfortable for him.
