I had this happen to a friend from college who stole a pretty decent amount of money from someone we knew. We were hanging out at his house, and it was like a party with a pretty good turnout. Later, he realized that he had about $1200 in cash missing. His parents were saving that money to buy a TV or something similar. Later, my friend told me that he stole the money when he was drunk. I couldn't believe he was capable of it. I started pressuring him to confess and told I would go and tell the guy's parents so they could file a report on him. He got a part-time job and started paying back the family, but we never talked again.
I will never have respect for thieves.
