My daughter's preschool read this book to her class, and my 4-yr-old daughter is now teaching the family when we are "dumping someone's bucket" or "filling someone's bucket". (I had never heard the phrase until she came home from school and reported to me how so-and-so dumped her friend's bucket. After a few minutes I realized that the bucket-dumping was figurative speech, and that my daughter now had a clear picture of what it's like to hurt someone else with your words or actions.) I've seen such a positive change in my daughter over the past couple of weeks. Now when I ask her to clean up a mess and she says, "ok, mommy" without a fuss, I can say right back to her "thank you for filling my bucket by putting your mess away, and you've filled it even more by not arguing with me about it." And for those times when she does argue about something, I can say with calm words, "you're dumping my bucket" and she totally gets the heart message of what I'm saying. It's awesome!
