The Five Keys

 Out of sight, out of mind
 so the story goes
 You forgot I exist
 My broken heart knows
 Out of sight, out of mind
 You found someone new
 But I can't change my love
 The way that you do
 I sit around a wondering
 About your new affair
 I should forget to remember
 And remember not to care
 I'd forget if I could
 But my heart is blind
 You are gone out of sight
 But not out of my mind
