Resisting temptation is never an easy thing. If there's something you want right in front of you, and you can take it, and nobody will ever find out, then why wouldn't you - even if you know it's not the right thing to do? A bus driver in Israel was faced with this dilemma, and a huge financial incentive to keep it to himself, when he was closing his bus down for the night and found a bag containing $25,000 in cash.
The owner's details were in the bag, and he could have easily returned the bag and any personal items to the owner without the money. Putting temptation aside, he returned the bag, money and all, to the owner. When he did, he found out the owner was a humble janitor, and the money represented savings he'd made over a long period of time to send home to his mother and children - people who were relying on him.
