Revenge is a dish best served cold. And according to Harriet, a girl from Cheshire, England, over a 17-year period. Harriet recently had the unfortunate luck of being cheated on by her boyfriend, Dan. You’d think a cheater would tuck tail, save what little face they had left and leave their SO alone, but Dan is a special breed of moron. Dan channelled his inner asshole and audaciously asked Harriet to pay him back for a Justin Bieber concert ticket he had bought for her.
