It's a Sunday morning. Linda goes shopping in a supermarket. It's very big. All the things there are very cheap because it's the first day for the supermarket, and there is a big sale.
There are a lot of people in the supermarket. And it is very crowded. Linda sees a little girl crying. She can't find her grandma.
"What's your grandma's name?" asks Linda.
The little girl doesn't know. She doesn't know her grandma's telephone number either.
Linda takes the little girl to the manager's(经理的) office. "Don't worry. Just stay with us and we can help you find your grandma on the radio." says the manager.
A few minutes later, an old woman comes. The little girl finds her grandma at last.
"Thank you so much!" The grandma says to Linda and the manager. Linda is very happy because she can do something to help others.
