Once the husband with his wife walking down the street. Soon they met a stranger, which started for no apparent reason to insult the man, telling him different shit and block the path, not letting them pass. Then the husband took from his pocket a small sum of money and handed it to the bully:
I mean, if this help. She'll you need, ' he said, and while the stranger was surprised, considered the money, took the wife on.
As soon as they strayed, a woman attacked her husband:
- You don't even know this man! He abused you, shamed on the street and you give him more money and gave? But why?
The man, somewhat embarrassed by the attacks of his wife, said:
- I gave him for drugs.
After some time this pair was back on the street. On the pavement in a pool of blood lay their recent offender.
The husband looked at his wife and whispered:
I told him that he will soon need money for drugs!
