Rosie Dutton, a teacher from Relax Kids in Tamworth, UK, used two apples to show her students the often unseen but harmful effects of school bullying(校园欺凌). She posted the lesson on Facebook, where it's been shared more than 160,000 times.

Rosie Dutton explained that during one of her classes she presented the children with two red apples. What the kids didn’t know was that before the lesson, she had repeatedly dropped one of the apples on the floor. And yet, on the outside at least, both apples looked perfect.

“I picked up the apple I’d dropped on the floor and started to tell the children how I disliked this apple,” Dutton wrote. “I told them that because I didn't like it, I didn't want them to like it either, so they should call it names too.”Some of the children looked at her as if she were “crazy”, but the students passed the apple around the circle, calling it names.

Continuing the exercise, the teacher then passed the second apple around the circle. This apple, however, was showered with words like: “Your skin is beautiful,” and “ what a beautiful colour you have.”

Dutton then showed the students both apples once again, stressing that “there was no change, and both apples still looked the same.”

Finally, Dutton cut both apples open. The apple that the class treated kindly looked fresh inside. But the other apple—the one they’d treated poorly —was bruised（瘀伤的) beneath its skin.

“I think there was a light bulb moment for the children immediately,” Dutton said. “When people are bullied, especially children, they feel horrible inside and sometimes don’t show or tell others how they are feeling. If we hadn’t have cut that apple open, we would never have known how much pain we had caused it.”

Dutton explained how important it is to teach children to stand up for one another, and to stop any form of bullying.

“Let’s create a generation of kind caring children,” the teacher wrote. “The tongue has no bones, but is strong enough to break a heart. So be careful with your words.”
