As a group, get your teacher’s approval to schedule a day to surprise the class next door with cookies and milk. Do this for no other reason than to spread good will. Encourage the class receiving the mini-party to repay the favor, but not toward your group but to another class. Watch as they plan to outdo your efforts by doing something nice—and unsuspecting—for another class down the hall. You might see a chain reaction where your original act of kindness makes its way through the entire school, perhaps even back to your group!
