Find a joke. Something like this. A child was called by his father to go shopping. The boss talks about price. The child doesn't know what to say, but it seems very cheap.

A joke I know is to let children buy things, but they are afraid that things are expensive, so I tell them to learn to bargain when buying things. For example, if the boss says 10, you only give five children "Oh". After arriving at the market, the child thought that his socks were broken and needed to buy a pair, so he asked the boss if they were the socks of seven wolves. Children in 22 yuan said it was 10 yuan. The boss looked at him and said, well, 15 yuan is OK. The method my father taught me was a brainwave. The boss said 7.5 yuan, the boss was sad. Oh, the child said it was 5 yuan as soon as he heard the door open. The boss said mercilessly, I gave it to you, and the child said, OK, I want one.

I wish you health and happiness.
