What is your take on outsiders telling off your child in public? Do they really have this kind of duty towards our own children?

I agreed with jinhui. I think most people will be not be such a busybody to step into disciplining a stranger's kid if the kid had not been a nuisance. If indeed my kid is in the wrg, n the stranger come forward to tell my kid off then I will accept it, because I failed to discipline my own child. But if my child is not in the wrg, then I will just ignore
