One sweltering day, I was scooping ice cream into cones and told my four children they could "buy" a cone from me for a hug. Almost immediately, the kids lined up to make their purchases. The three youngest each gave me a quick hug, grabbed their cones and raced back outside. But when my teen-age son at the end of the line finally got his turn to "buy" his ice cream, he gave me two hugs. "Keep the changes," he said with a smile.有一天天气闷热，我将冰淇淋舀进锥筒，告诉我的四个小孩，他们可以从我这里用拥抱“购买”一筒。于是，孩子们马上排起了队来购买。较小的三个孩子每人很快的抱了我一下，抓过冰淇淋筒就跑到外面去了。最后轮到排在队尾十岁的大儿子来“买”冰淇淋时，他拥抱了我二下。“不用找了，”他笑着说。
