One Drop of Kindness is a heavy-hitter in the social-emotional learning category. It doesn't just tell kids to be nice; it gives them a framework for understanding that people who act out are often just people who haven't been shown a better way yet.

It's a bit on the didactic side—you're definitely getting a lesson with your story—but for parents trying to build a culture of empathy at home, it's a useful tool. It's the kind of book that works best when you read it together and then actually look for 'drops' to do in the real world the next day.
