Robert Louis Stevenson

Gather ye roses while ye may,
Old time is still a-flying;
A world where beauty fleets away
Is no world for denying.
Come lads and lasses, fall to play
Lose no more time in sighing

The very flowers you pluck to-day
To-morrow will be dying;
And all the flowers are crying,
And all the leaves have tongues to say,-
Gather ye roses while ye may.
