What moment makes you feel that there is a generation gap between you and your parents?

Clothes with holes are particularly popular recently, and I bought myself a suit following the trend without exception.

One day, I came home wearing clothes that I thought were fashionable, and my mother almost cried, saying that the child was so frugal. This dress and trousers are torn, so I still wear them. As soon as my voice fell, I picked up a needle and thread and sewed it for me. How big is the generation gap?
