Have student wrinkle up the paper heart (not tearing it) and then try to flatten it out. Discuss how words or actions can harm a heart and take time to heal. Good first week of school activity or for an anti-bullying activity.
Lots of people today need to really THINK before they speak. Too many people have forgotten how to be kind and speak with respect. The saddest part for me is that children are watching and learning how to imitate the same behavior.
