DIXON – Sitting in an auditorium full of high school students, Brittany Skibinskie closed her eyes and thought about her great aunt.

She was at an assembly on Rachel’s Challenge, named after Rachel Scott, who was one the first of 13 people killed during the Columbine High School shooting in 1999. After her death, Scott’s family discovered her writings in which she argued that a kind act can result in a chain reaction of kindness.

One of the challenges the speaker, DeeDee Cooper, had for the kids was to tell the people they love how much they care.
