One day, Sally asksher friend Anna, "I have so many new clothes, but I'm not happy. You don'tbuy new clothes, but you're always happy, why?"

"Oh, dear, I don'tthink new clothes can make one happy," says Anna." But what makes youso happy?" Sally asks.

"Helpingothers" Anna says." I often go to the old people's home (敬老院) with my sister Gina. Gina tidies rooms for them and I play gameswith them."
