How to be an Asshole
Do something rude.
Make sure to realize that what you did was a huge infraction. Unforgivable. Your friends or coworkers will always remember that thing you did and your character is now permanently besmirched.
Don’t make an effort to apologize or clean up the damage you caused, because your friends will no longer accept you.
Seeing your friends reminds you of the damage you caused. Distance yourself further from these people.
Seek out an entirely new group of people. People who weren’t there for your unforgivable behavior.
