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.
In  William Shakespeare’s ‘As You Like It’ there is a charachter whose name is Amiens. This poem is a song sung by him. In these first three lines, he comments that the wind may blow as hard is it likes, because its harshness does not compare to that of a man’s ungratefulness.
