A FRIEND SHOULD BE RADICAL:

HE SHOULD LOVE YOU WHEN YOU'RE UNLOVABLE.

HUG YOU WHEN YOU'RE  UNHUGGABLE

AND BEAR YOU WHEN YOU'RE UNBEARABLE,

A FRIEND SHOULD BE FANATICAL ;

HE SHOULD CHEER WHEN THE WHOLE WORLD BOOS,

DANCE WHEN YOU CRY, TOO.

BUT MOST OF ALL, A FRIEND SHOULD BE MATHEMATICAL, 

HE SHOULD MULTIPLY THE JOY, DIVIDE THE SORROW,

SUBSTRACT THE PAST AND ADD TO TOMORROW,

CALCULATE THE NEED DEEP IN YOUR  HEART,

AND ALWAYS BE BIGGER THAN THE SUM OF ALL THEIR PARTS.
