One of the first people that I met on arrival was the house "father" where the shirt ripper himself is accommodated. He is a wonderfully gentle man in every sense, and he reassured me that he had reinforced the idea of no clothes removal with the boy who dribbles.
He also gave me some advice.
Always reply in the positive and it avoids confrontation.
So when the boy who dribbles asked again whether music was finished and if it was time for poneys, I replied "yes, it will soon be time for poneys" and not "No, it isnt time for poneys yet!"
And, it worked. He was happy.
My colleague who had the collision with the radiator has not been so lucky though. She is on sick leave with deep bruising of her spine until at least the middle of June...
