The holiday season may purport to bring out the best in us, but it can often bring out the worst. The collision of families, the emotional intensity of the celebrations, the sky-high expectations… it can be the perfect storm of family tension. I heard once that the time you're most likely to get murdered is on Christmas day, by the hands of a family member. So much for merry and bright. So it's no wonder that the holiday months can also be the perfect time for exacting revenge on one's enemies. I think it was Sun Tzu who said, "Revenge is a dish best served beside a glistening turkey on Thanksgiving."
This story from r/pettyrevenge is a delicious example of seasonal animosity, flawlessly executed. After all, food is the centerpiece of holiday celebrations, so it follows that it's the perfect way to get the better of a sworn enemy.
