I had a teacher in third grade send me to the vice principal’s office because my handwriting was, and is, terrible. His idea of dealing with a 9 year old whose handwriting is bad was apparently that if you scream at them hard enough, their good handwriting will just come out. They apparently decided to not inform my parents of this event, so they were quite surprised when I came home and started apologizing because I got in big trouble at school.
Well, my dad went up to the school and showed them he could scream, too. Sent the teacher to the staff room in tears, and the vice principal suddenly lost his volume when he’s faced up against a 6’2 farmer instead of a 9 year old. Neither of them tried anything like that again.
