"A guy was driving for hours in a desert.

Suddenly he is faced with a simple gas station with a gas station and only a man of about about 70 years old, sitting in a rocking chair and old next to him was a dog. The boy in the car and says:

...- Lord, please, fill the tank for me.

You stood up and began to fill the tank.

While doing so, behold the young driver could see the reaction of the dog who cried and stopped, and stopped crying. The driver with the agonizing fact question to you:

- That dog is the master?

- Yes - you answered.

- Then answer me why he cries and to cry and to?

You answered:

- It's because he's sitting on a nail.

- So why not raise it and then leaves? - Asks the boy.

- "It should not be hurting so much - it hurts you enough to complain, but not enough to move" - you answered.

Moral
Many people complain about everything, complain of life, financial situation or the people around, but do nothing to get off the nail.

Think about it and not sit on the nail!
