So what if you go out of your way for someone?

Nice gestures don't always pay off. It's not like you'll ever be reimbursed for your trouble that they put you through. A simple "thank you" sometimes would suffice, but they act like spoiled brats and you're supposed to do these things for them. The only way you get through it is coming to to the realization that they are obnoxious, arrogant, self centered, dumbasses who are going to go no where in life because of the choices they have made. You can always sink to their level and tell their significant other that you slept with them, but you know that will solve nothing in the end. Even though having sex with that significant other really was really a warning sign in itself because the only real pleasure you ever got came from making fun of it later with your friends. Instead you live your days knowing that someday someone will do something nice for you, even though it might not be the same.

To those obnoxious, arrogant, self centered dumbasses I say this: You know how when you're walking past a group of people, you hear them laughing and you sometimes get that paranoid self-conscious feeling? Maybe they're laughing about you when they're really not? Well, in your case, they really are.

You're a little engine that couldn't hold it's load.
