Random Acts of Kindness (RAK) Week (February 11-17, 2018) is a week-long celebration of kindness. RAKtivist is short for Random Acts of Kindness activist. Think of RAKtivists like kindness ambassadors—and, like all ambassadors, they’re a part of an active, global community. RAKtivists are everywhere. The student who stops to hold the door open for a teacher with her hands full? That person is a RAKtivist. The commuter who offers their bus seat to an elderly passenger? That person is a RAKtivist too. The parking attendant who leaves a note on someone’s car, complimenting their parking skills? You guessed it: RAKtivist.
