#1.) Line-Cutters. Your first option is to just ignore them and let them cut in. But if you can't let it slide, do three things: First, make sure you don't act angry or they'll get defensive.
#2.) People Who Love Arguing, Even When They Know They're Wrong. This one's tough, because you're dealing with someone who's irrational. So the best approach is to try avoiding the argument altogether.
#3.) Overbearing Family Members. The best thing to do is set clear boundaries so they don't get under your skin too much. But since you don't want to create drama, you also have to choose your battles and let some of the small stuff slide.
#4.) Friends Who Are Never on Time. If you want to teach them a lesson, just stop waiting for them. For example, if you're supposed to have dinner with friends, the whole group shouldn't sit there hungry just because one person is late.
#5.) Noisy Neighbors. Chances are they don't know they're being so loud. And if you just knock on their door and ask them to keep it down, they will.
