> then when you have your own kids you will start seeing your parents in different context as you became parent and see you was maybe more harsh on them than they deserved

Is this really so common or just something a writer said once? Because I definitely went the opposite way. And genuinely, I never seen anyone say that they did became more understanding toward stuff that bothered them the most when they were younger.

I know both people who try to emulate parents with own parenting and those who are firmly decided to do things differently. (Most have both aspects.)
