The teacher's note about the gift had been lost in my brother's coat pocket but found at the last moment. It read, "Buy a present for a boy. Please spend five to ten dollars."

　　Paul and Mom had walked to the store looking for something good and finally settled on a Duncan butterfly yo­yo. The yo­yo was popular at school and it was seven dollars, so this one was well within the teacher's suggested amount. That was exactly what Paul needed to exchange with another boy. They bought it immediately.

　　"So，" Mom asked again, "what did you get？"

　　Paul opened his hand and showed her a small broken­down old car. My mother held it in her hand. "Really？" she asked. "Who gave it to you？" She tried to cover up her disappointment. Who would give a broken old toy car when the note had clearly said, "Spend five to ten dollars"？

　　"Andy，" Paul said, looking down at the car. "Isn't it great? It's his favorite. And he gave it to me! I am his good friend."

　　Hearing his words, I was deeply touched. Paul always taught me to give generously and to receive thankfully - from my heart.
