Quotations
Blow, blow, thou winter wind,
Thou art not so unkind
As man's ingratitude:
Because thou art not seen,
Although thy breath be rude William Shakespeare As You Like It Time hath, my lord, a wallet at his back,
Wherein he puts alms for oblivion,
A great-sized monster of ingratitudes:
Those scraps are good deeds past: which are devoured
As fast as they are made, forgot as soon
As done William Shakespeare Troilus and Cressida How sharper than a serpent's tooth it is
To have a thankless child! William Shakespeare King Lear Neither cast ye your pearls before swine Bible: St. Matthew View usage for:All yearsLast 10 yearsLast 50 yearsLast 100 yearsLast 300 years
