It is really interesting to see how a change in perspective brings out a totally different person in us.
Many of us must have been pretty difficult kids, until we became parents.
It is easy go criticise authority, until we ourselves are in those shoes and have to walk those miles.
I once had a pretty difficult class to teach. The students were unusually noisy. Then there was the day, some of the students wanted to make announcements and none of their classmates would listen. Then the realisation surely dawned on some.
