Re: 9 year old girl saved money to buy a lot of toothpaste. Her mother was puzzled until the day came.
mother asked her why she did not have to buy these things, and the girl smiled and said, "I'll tell you when the time is good."
all of a sudden one day, the girl stopped buying articles of life and asked grandma how to make a knapsack. Grandma is curious. What does this girl do?
