" The flower that smiles today
Tomorrow dies;
All that we wish to stay
Tempts and then flies;
What is this world's delight?
Lightning, that mocks the night,
Brief even as bright.--

Virtue, how frail it is!--
Friendship, how rare!--
Love, how it sells poor bliss
For proud despair!
But these though they soon fall,
Survive their joy, and all
Which ours we call.--

Whilst skies are blue and bright,
Whilst flowers are gay,
Whilst eyes that change ere night
Make glad the day;

Whilst yet the calm hours creep,
Dream thou - and from thy sleep
Then wake to weep. "

― Percy Bysshe Shelley
