What grade school grudge do you still hold on to after 3 decades?

In grade 2, my dad got me a crayon set from a business trip. The crayon set had gold and silver, which none of the other kids have, they were my favorite and I used them very sparingly.
Then, one of the kids on my class asked me to use my gold and silver pens for a homework. I refused, but then he went to the teacher who forced me to share them.
Next day, they get returned to me from full pencils to 1/3 and a practical knub. His paper had no blank space, all gold and silver.
Olivier, you bowl cut snot nose sounding dastardly, if you're out there, above or below ground, know that I have never forgiven you.
