Talking of catholic schools, mine were of that persuasion. I can believe they'd come out with rubbish like that boat, although I don't actually remember left handers being discriminated against during my school days, I think they'd moved on a bit by then, at least from the concept of left handers having a deviant streak. I do however remember falling out of a tree and breaking my arm when I was at juniors. As luck would have it, or not, it was my right arm in plaster, so I was forced to write with my left hand, and then got told that my handwriting was a disgrace
Understanding people not!
