When the person who you trusted more than anyone else betrays that trust, it’s reasonable for you to be angry. It is NOT reasonable for you to destroy your former partner’s things, steal their dog, or buy a billboard with their face on it next to some bright lights that read “CHEATER” (that’s a huge waste of money for something so trivial).
Instead, next time you find yourself in a situation less than optimal, take a tip from this guy and turn to wit. After discovering his girlfriend was cheating on him, he extracted revenge with this excellent card. No violence, no broken glass, just a card and the sweet, sweet look on her face that we can only assume was ghostly white. Nice job!
