Many years ago, I step into a bookstore for some 
 books I wanted them. While I was there, I saw a young 
boy of about 12 came into the store. The boy wanted 
to buy a geography book. Geography books paid
one dollar every, but he had only 62 cents. I decided 
to follow him to see whether she could succeed. Four 
stores we entered, and four times he disappointed. 
Luckily at the fifth store he got an used book for 50 
cents. Having learned why he wanted the book, and 
the bookseller gave him some writing papers and a 
new pencil as a gift.
