to whom I should never extend

I'm busy!
I am building
     a model, of an entirely
          new
               heart!

A heart
     for the future: to feel
          and love with. A heart
               to understand men with:

And also, to tell me, whom
     I should freely
          shake by the hand--
and to whom
     I should never
          extend it.
