    Victory Bacelis is a California immigrant（移民）who grew up in a poor village in Mexico. He is used to working hard. He works more than 90 hours a week at three different jobs, including McDonal's. He is saving up to buy a house.

    One day, while Victory was cleaning the floor at McDonal's, he found an envelope and picked it up. There was $612 in it. He called the police to report the lost money. The police couldn't find the owner, so they gave the money back to Victory.
