There was a boy in our class called Wilhelm Luttich who had a speech impediment. We must have been twelve or thirteen. Poor Wilhelm had trouble in French saying "Je suis". He always said "Je Tswee, je tswee." The more he tried, the more he failed. Our teacher got so annoyed Wilhelm couldn't say "je suis", he gave him the whacks. So we all got up in arms about it, and said it wasn't fair. So then we all got the whacks. We had to bend over and he whacked our bottoms once. Elfriede as well. That was the way it was.
Later Wilhelm became a bank manager in Goslar. He was a very clever boy. But he never could say "Je suis".
