BLOW, blow, thou winter wind,
Thou art not so unkind
   As man's ingratitude;
Thy tooth is not so keen,
Because thou art not seen,
   Although thy breath be rude.
Heigh ho! sing, heigh ho! unto the green holly:
Most friendship is feigning, most loving mere folly:
   Then heigh ho, the holly!
   This life is most jolly.

Freeze, freeze, thou bitter sky,
That dost not bite so nigh
   As benefits forgot:
Though thou the waters warp,
Thy sting is not so sharp
   As friend remember'd not.
Heigh ho! sing, heigh ho! unto the green holly:
Most friendship is feigning, most loving mere folly:
   Then heigh ho, the holly!
   This life is most jolly.

- William Shakespeare, As You Like It, Act II, Scene VII.
