To whom it may concern,   

     My sincerest apologies, 
     I know
     it was my fault.
     I let my heart
     speak, rather than listening
     to my brain—
     it’s only
     “book smart”
     though so you
     shouldn’t have trusted me
     in the first place.
     I was “selfish” you
     snarled as your teeth
     wrecked together. I guess
     it could be screwed that way
     if you think
     about it long enough.
     Once again,
     my bad.

       Someone who should
               have tried harder
