I over heard the cutest converstion at work the other day. One of the musicians that was playing had just finished a song, with an expression on his face of hopeful expectation. A girls across from him told him that he had dropped something. The musician rolled his eyes waiting for applause. She happily said "you dropped your smile. Now pick it up".
Smiling is contagious. Once someone starts it spreads so quickly.
I smile with customers...
I need to smile more at home for no one but me.
