As a former worker in many types of education establishments I can agree that children act out prior experience..verbally and physically..
it is a good worker (and citizen) who shows respect at all times for other people..animals and belongings.Buildings and vehicles included.
listen to people speak read their words...it soon becomes clear what agenda people have..
treat others as we wish to be treated..whole programmes are built round that ethos..as many childrens authors establish that Golden Rule it is a way of life and education is only one part.Undoing early abuse is the special educational teachers first task..
