A beautiful one from Emily Dickinson. Liked it so much that I am posting it here -
Heart! We will forget him! by Emily Dickinson
Heart! We will forget him!
You and I -- tonight!
You may forget the warmth he gave --
I will forget the light!
When you have done, pray tell me
That I may straight begin!
Haste! lest while you're lagging
I remember him!
