Turn out

A small boy was back home from school, when reaching near ther door, he suddenly heard a man voice courting his mother, come from inside the house.
This night, I will wait you at the usual place! Remenber to be on time, my little cucumber!
So angry but didn't know what to do, the boy took a brick and threw at the door. His mother ran out and shouted:
What do you do so noisily?
Nothing! I just threw a cat intending to eat stealthily a cucumber in our kitchen cabinet!
The man understood, turned pale, bent his head and ran away!
