Tell me, what have you done to make your parents sad?

It's my mother's fault that she went out in a rage and didn't answer her parents' phone calls, but I don't know if it was my father who dialed the phone again and again, because no one answered the phone, worried that something was wrong. At two o'clock in the morning, my father sent two short messages, and tears began to flow downwards, but he stubbornly refused to express it. I hope that in the future, I will never do anything that makes my parents sad again!
