There is a Jewish story

There is a Jewish story, an ordinary Jewish joke: A father was teaching his little son to be less afraid, to have more courage by having him jump down the stairs. He put his son on the second stair and said 'jump, and I'll catch you' then on the third stair and said 'jump, and I'll catch you', the little boy was afraid, but he trusted his father and did what he was told and jumped into his arms. The father put him on the next step and then the next, each time telling him 'jump, and I'll catch you'. Then the boy jumped from a very high step, but this time the father stepped back and the boy fell flat on his face. He picked himself up, bleeding and crying, and the father said to him, 'that'll teach you.
