Collingswood Middle School’s Kindness Club wanted to push back against some of the hate in today’s world, so they took to the classroom.

The group left “Third Party Compliments” boxes in three classrooms for two months with the instructions to leave a note saying something kind about someone you know – and they were left with plenty of nice things to say.

Each student read their compliment on camera, and seventh grade teacher Sarah Whitman posted the kids’ reactions to YouTube. Watch below!
