William Shakespeare Quote

Seems, madam! Nay, it is; I know not 'seems'.
'Tis not alone my inky cloak, good mother,
Nor customary suits of solemn black,
Nor windy suspiration of forced breath,
No, nor the fruitful river in the eye,
Nor the dejected 'haviour of the visage,
Together with all forms, modes, shows of grief,
That can denote me truly.

Hamlet (1601) act 1, sc. 2, l. 76
