2. You Sabotage Someone's Life For Fun
This one is kind of a big giveaway that you're an awful person, especially if you write said plan on a whiteboard and cross off each successful sabotage like an evil genius. Just don't make the mistake of using a permanent marker because that's just karma biting you in the bud. If someone has wronged you, it can be difficult to forgive and forget so you need to be the bigger person in the situation and act like adults. And even if they do have a fat ass, don't call them a fat ass in front of everyone, especially if you've made them a fat ass.
