A woman who ran to the mall for a quick errand lost her purse, but an honest teenage boy returned it to her.
The woman looked inside her purse and remarked, "That's strange. Earlier I had a $20 bill inside, but now it's gone, and instead I see two fives and a ten."
"That's right," the boy explained. "The last time I found a lady's purse, she did not have change for a reward."
