A Very Old Man with Enormous Wings

I have to say, this is one of weirdest stories I have read for this class yet.
When I say weird I mean angel falling from heaven and living in a chicken cope type of weird. I suppose there is symbolism within each element. Like him being in a cage could represent the feelings we have as being trapped in a situation or in a particular place in society. Perhaps the throwing of the rocks at the angel represent Stephen the Matyr. Maybe just maybe the author knew a man who lived in a chicken cope. All of these questions may seem weird but reading this story that is what I was left with, questions.
The author was interesting, born in Columbia, close with his grandmother and loved telling stories. I imagine that he is inspired by the stories he has heard from his family. As if as a child he climbed into his grandfathers lap and listened as he told of war tales and or love.
I can relate to the author in this feeling of inspiration. My grandparents have beautiful stories and often times I will go to their house to hear them tell me of their days. I sometimes cannot avoid them. I will be doing something in the kitchen and from across the house my grandmothers voice rings in the air "in my day we walked to school in the snow".  I may laugh and joke with her at the time but these stories she tells me leave an imprint in my heart. I desire that my house one day is filled with stories, stories of the past, present and future.
I am not sure if this is what the story was supposed to evoke but it definitely got me thinking of the beautiful memories of my grandparents.
I am not sure why exactly this story matters in my life, but to someone, somewhere this story tells a tale deeper than what I have read.
