Robin
Be somebody's cheerful hello.
What this friend is telling you
In the coldest, grayest part of winter, the robin shows up on the snowy holly branch with its bright orange chest — and sings anyway. One small robin changes the feel of a whole frozen yard. You can be that. The "good morning" to the bus driver. The wave to the kid at the window. The first laugh in a too-quiet room. It costs you nothing, and someone out there is having a winter.
Try this
Tomorrow, be the first hello three times. Count how many smiles you get back.
