Need suck with themesread and give me the theme and why it's the theme: when i do count the clock that tells the time, and see the brave day sunk in hideous night; when i behold the violet past prime, and sable curls all silver’d o’er with white; when lofty trees i see barren of leaves, which erst from heat did canopy the herd, and summer’s green all girded up in sheaves, borne on the bier with white and bristly beard, then of thy beauty do i question make, that thou among the wastes of time must go, since sweets and beauties do themselves forsakeand die as fast as they see others grow; and nothing ’gainst time’s scythe can make defencesave breed, to brave him when he takes thee hence.
