Also went to Catholic school, grade 1, 1958 in Toronto. Soeurs de la Miseracordes, french nuns, same prejudice. Told my Dad what they were doing, he let them have it as he abhorred bullies. The penguins left me alone. Next year, my brother went into grade 1 as a lefty and remained one to the day he died.
