[The Hogwarts Sorting Hat]

Ask to share the cheat-sheet. This test isn't fair, so why should you be? Confront them after the test and force them to tell the teacher they cheated, or you will tell on them. They must pay for their misdeeds. Confront them after the test and try to convince them not to cheat anymore. You don't want them to get in trouble. Good for them, they beat the system.

Leave it there. Someone is probably looking for it. Pocket the money. You don't know who it belongs to, so finder's keepers. Take it to the police in case anyone ever reports it. Take the wallet, and go around the area asking anyone if they have lost a wallet recently.

Laugh along with the crowd. You love a good joke even if it's at your expense./That jerk! You get mad right away and tell it to their face. On the outside you'll laugh because you don't want anyone to know that they really hurt your feelings by making you look stupid in front of everybody. Pretend that all is well, but you won't forget this. They're going to pay for what they did! How dare they publicly humiliate you. You get upset and run away from the crowd. How could they be so mean?

Let him yell, it doesn't matter anyway, you're not listening. Allow him to yell all he wants, you'll just let the air out of his tires someday. Endure his yelling, he is my boss after all. Explain to him that accidents happen and that you don't feel you need to be yelled at because of it.

Ask them what's wrong with the car. Maybe you can talk them through how to fix it. I'll do it, but I'm charging them for gas money. I'm too tired. Make up a lie about why you can't help them. Yes, I'm tired, but what are friends for?
