Good Morning Addison, 

Today is December 1st, and the first day of our month of helping others. Are you excited? Today I want you to write a sweet note for our mail lady, and leave a treat in the mail box for her. She will be so excited to receive something special from you. And you will feel good about doing it. 

Have a great day Addison! See you tomorrow.

Love, Calvin

 And later that day we checked the mail and found a note from Donna, our mail lady!
