I could also give you an example of how this could work well for a parent if you like, Bernadette.
I had taken my fifteen year old twin boys to the doctors. We had been sat waiting for a while when a very harrassed young woman prepared to leave with her 2-3 year old son. Could she catch him? Could she hell!!! He ran one way, she ran after him. He ran the other way and she ran that way. Others in the surgery tried to help her but the little terror was too fast on his feet.
One of my boys turned to the other. 'This would never have happened to mum!' he laughed.
'Yeah!' the other twin said,'Mum would have just said, 'I'm going!' and have left! She always means it! And we always had to run after You!' he said pointing to me and laughing, 'Because we knew you MEANT it!'
Bringing up children is little effort if you use your brain first and only!!
