Edna St. Vincent Millay said this quote

I know I am but summer to your heart,And not the full four seasons of the year;And you must welcome from another partSuch noble moods as are not mine, my dear.No gracious weight of golden fruits to sellHave I, nor any wise and wintry thing;And I have loved you all too long and wellTo carry still the high sweet breast of Spring.Wherefore I say: O love, as summer goes,I must be gone, steal forth with silent drums, That you may hail anew the bird and roseWhen I come back to you, as summer comes.Else will you seek, at some not distant time, Even your summer in another clime.
