Are you smiling? Have a happy day.

There is a form that springs from the heart, heard every day in the merry voice of childhood, the expression of a laughter-loving spirit that defies analysis by the philosopher, which has nothing rigid or mechanical in it, and is totally without social significance. Bubbling spontaneously from the artless heart of child or man, without egoism and full of feeling, laughter is the music of life.

William Osler
