Who says honesty is dead? Last Tuesday morning Alan Reed, a student, was at the bank. He asked to take out $ 50 but the bank clerk mistakenly gave him five twenties instead of five tens. For a few seconds he wondered what to do. Should he give the extra money back? Keep it? If he kept it, he could buy several new books, or he could take his friend Alice to a fancy dinner.

Then it occurred to him that the lady would probably get in trouble. Worst of all, Alan felt, he would probably feel guilty about keeping the extra cash. So Alan gave back the money.

The bank clerk was so impressed that someone was honest enough to return money not rightfully his that she contacted the newspaper. So there you have it. What would you have done if you’d been in Alan’s position?
