Carpe diem- william shakespeare

O mistress mine, where are you roaming? O stay and hear! your true-love's coming That can sing both high and low; Trip no further, pretty sweeting, Journey's end in lovers' meeting-- Every wise man's son doth know. What is love? 'tis not hereafter; Present mirth hath present laughter; What's to come is still unsure: In delay there lies no plenty,-- Then come kiss me, Sweet and twenty, Youth's a stuff will not endure.
