Breakups are hard on everyone involved, but some take them harder than others. It's never fun to realize that things aren't working out, or even worse, that the person you invested so much time and emotion into is a jerk of colossal proportions.
It might not be mature, but it's still understandable when somebody wants to get their own back on an ex. This seemed to be the reasoning behind @katieber5 sharing her petty revenge against her former partner, which involves sticking a fish through their front door every day.
While some were less than impressed with her devious prank, others applauded her dedication to the cause. Perhaps closure doesn't exist, but many creative ways to make a heartbreaker miserable certainly do.
