Robert Frost " Birches"

Mr. Frost seems to love analogies, along with winter settings, in this poem he seems to be saying indirectly that the rigidness of life is plastic, it can be molded and shape and changed, we think of the branches as a father figure in this poem. The boy swings on the branches, ventually changing what seemed to be impossible. What can i say Mr. Frost loves to leave it up to interpretation. He could be just going on a tangent about trees..lol
