Shakespeare's (O Mistress Mine)

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;
Journeys 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 not plenty;
Then, come kiss me, sweet and twenty,
Youth's a stuff will not endure.
