Be kind

This is at the Phoenix headquarters of Ben's Bells, which is a Tucson-based program that promotes kindness. It is named after Ben, a woman's 3-year-old son who died in 2002. To help heal, she made bells and hung them in trees around Tucson.

Its website says: "The mission of Ben's Bells is to teach individuals and communities about the positive impacts of intentional kindness and to inspire people to practice kindness as a way of life."
