Kara likes getting e-mail from Fumi. Kara is a third-grader in Arizona(亚利桑那), and Fumi is in third grade in Japan.They are e-pals who send e-mails every week. Fumi sent Kars photos and descriptions of her home.

The first room in Fumi’s house is a small entryway. People who enter the home remove their shoes. They put on different shoes with soft soles. That seemed odd ot Kara. She wears her street shoes in the house.

Kara likes the photo of Fumi and her family eating. They gather around a table, just like Kara and her family, Kara’s family sits on chairs, but Fumi’s family sits on cushions on a strau mat on the floor. The table is low to the ground. What seems to be a wall behind Fumi’s family is actually a door without knobs. Fumi explained that the door slides open. It is made from strong paper glued to thin strips of wood. “I could never play ball in that house!” thought Kara.
