Like a bird in a cage example of metaphor

you only use like or as in similies, to make it a metaphor take out the like

in   ¨and yet the books¨   by czelaw miloz the tone is positive since it tells us that when we touch a book, it starts to live and the perspective is in the third person and turns once into the first person. in "the rhinoceros" by eugene ionesco the tone is illogical and absurd   and the perspective is in the third person since it is a play.

it is an infinitive phrase with a subject.
