Thinking about garden, it's seemed to me that in the garden must contained lots of trees and flowers. For me garden must be colorful and has animals for instance butterflies. Many people plant garden because its make their place look more attractive and beautiful. When they're looking in their own garden, they would feel relax and comfortable. Some people can stay in the garden all they, it's special place!

The boys go to the seed store to buy some seed for planting and the old woman, the owner, sell them a cosmos seeds with special prices. After that, the boys immediately go to scatter cosmos seed over the old man's yard and then they help together to fix the old man house. While they watch the reborn house, Kawabe asks the old man about his family but the old man knows nothing, therefore Kawabe is angry because he's think it the old man fault that his father married twice.
In my opinion, the boys help the old man because they want to know more about him, in another word, spying the old man. Moreover, the boys know that the old man can't bent his knees ,so it's better to help him. For the old man, I think he try to teach something for the boys. He also want to observe about these boys. While they're observation each other, their relationship continue to grow better and better.
