The way to love anything is to realize that it may be lost.
My Pretty Rose Tree
by William Blake
A flower was offered to me;
Such a flower as May never bore.
But I said I've a Pretty Rose-tree.
And I passed the sweet flower o'er.
Then I went to my Pretty Rose-tree:
To tend her by day and by night.
But my Rose turnd away with jealousy:
And her thorns were my only delight.
