It isn't the thing you do; 
    It's the thing you leave undone, 
    Which gives you a bit of heartache 
  At the setting of the sun.
The tender word forgotten, 
    The letter you did not write, 
    The flower you might have sent, 
    Are your haunting ghosts tonight.
The stone you might have lifted 
    Out of a brother's way, 
    The bit of heartsome counsel 
    You were hurried too much to say.
The loving touch of the hand, 
    The gentle and winsome tone, 
    That you had no time or thought for 
    With troubles enough of your own.
The little acts of kindness, 
    So easily out of mind; 
    Those chances to be helpful 
    Which everyone may find —
No it's not the thing you do, 
    It's the thing you leave undone, 
    Which gives you the bit of heartache 
    At the setting of the sun.
