Told little Vovochka friends that all adults have any secret and therefore very easy to blackmail. Vovochka decided to check it out and came home after school, the mother said gravely:
I know!!!
Mom turned white and put Vovochka $ 20.
— Don't tell dad!
Vovochka loved it and when dad came home from work, he told him:
I know!!!
Dad nervously looked around and gave Vovochka $ 50:
— Mom no words!
In the morning Vovochka was met by the postman near the gate.
I know!!! said Vovochka the postman.
The postman dropped the bag, a tear glistened on his cheek, and, spreading his arms to embrace him, he shouted:
— So go on, hug your dad, son!!!
