Each of us need critics,
But all of us need friends;
To know the role you’re playing
Is wisdom without end.
Some criticize for pleasure,
Some criticize for love,
Some criticize and never know
Which they’re guilty of.
For that green worm of jealousy
Can creep into a heart
Disguised as helpful caring
And force dear friends apart.
