     One day in early March of 1993, Pauline and Tom Nichter and their 11-year-old son Jason, were shopping

for a toy in Buena Park. Suddenly, Pauline saw a wallet lying on the floor. When she looked inside, she found

$200. The family, homeless and without work, knew that could change their lives. But they took the wallet to

the nearby police station and turned it in. The wallet was found to have some other pockets, and more money

in-over $ 2,000! The police called the man who lost the wallet to pick it up. The man thanked the Nichters and

shook their hands, but did not reward them. Luckily for the family, a TV news reporter filmed the story. People

from all over the world heard the story and sent them letters, money and even jobs. A businessman even let them

live in his house for free for six months. So far, the family has received over $1,000,000. Now the Nichters'

future is bright.
