When Julio Diaz stepped off the subway after work one night, he was simply planning to go to his favorite local diner for a meal. But when a teenage boy approached him with a knife, Diaz knew the evening was about to take a more dramatic(巨大而突然的) turn.

The young man demanded Diaz’s wallet, and Diaz passed it over without objection(异议). But just as he turned to walk away, Diaz called, “Hey, wait a minute. You forgot something.”

The young man turned around, surprised.

“If you’re going to rob people for the rest of the night, you might as well take my coat to keep warm.”

The teenager looked at Diaz in disbelief, and asked why he would do such a thing. Diaz replied, “If you’re willing to risk your freedom for a few dollars, I guess you must really need the money.”He said he was heading out for dinner, and that he would be happy to take someone with him.

The young man decided to take Diaz up on his offer. As they were sitting at the table, the manager, dishwashers and waiters all stopped over to say hello to Diaz, and the young man was amazed at his popularity.

“Haven’t you been taught that you should be nice to everybody?”Diaz asked him.

“Yeah, but I didn’t think people actually behaved that way,” the teenager replied. Thanks to Diaz, he was beginning to see that kindness wasn’t so strange, after all.

When the bill came, Diaz told the teen that he’d have to get the check. After all, he still had Diaz’s wallet.

But the teenager put the wallet on the table without a moment’s thought, and Diaz treated him to dinner. Diaz also gave the would-be robber a $20 bill — in exchange for his knife. “I figure, you know, if you treat people right, you can only hope that they treat you right,” Diaz said.
