When Zach shoves his little brother to the floor, he knows he did something wrong. Even so, itâ€™s hard to apologizeâ€”especially when he feels Alex kind of deserved it! With his Momâ€™s help, Zach learns the â€śfour-squareâ€ť apology: 1) say what you did; 2) say how it made the other person feel; 3) say what you could have done instead; 4) make it up to the person. Family counselor and psychotherapist Mulcahy wrote the Zach Rules series to teach children social skills and provide practical coping tools for working through the issues that are typical of kids ages 5 to 8. Also available is Zach Gets Frustrated, sold separately for $14.95 Illustrations by Darren McKee.
