Grant me but a day, love,
But a day,
Ere I give my heart,
My heart away,
Ere I say the word
I'll ne'er unsay.
Is it earnest with me?
Is it play?
Did the world in arms
Cry to me, "Stay!"
Not a moment then
Would I delay.
Yet, for very love,
I say thee nay.
Ere I give my heart,
My heart away,
Grant me but a day, love,
But a day!
Mary Elizabeth Coleridge
