Britain banned any type of physical discipline in schools, that is why pupils can now ride roughshod over the teachers. How many of us can remember a black board rubber come whizzing past your ear, or "I am going to have a word with your parents" Today they look at you and shrug.
I remember a time sitting in a hospital waiting room, my son was only young, his appointment time came and went, he started to get fractious, throwing himself about as the pain got worse, I am his mum and knew that the signs were going to get worse and he was going to hit, so I pulled him to me and hugged him, he squirmed and shouted, A woman, came over to me and told me off for restraining him as it could be hurting him, that as a mother I should see this and telling me to let him go, so I thought well OK I will you bl00dy knowall do gooder, I let him go and he ran off in her direction and promptly kicked her in the shins.
Sometimes, these do gooders and know-it-alls should keep their snouts out of what is going on, remember, because someone looks normal you never know what problems they do have.
