<span>One of the most oppressive physical elements about Esperanza's situation that she reacts to is actually the poverty that she and her family faces, and the way that this traps them in their house which Esperanza feels so ashamed of and also gives Esperanza such an intense desire to improve herself and study so that she can escape and buy her own house.</span>
Quite similarly, ever since I was a young kid I used to dream about going to London, it was my life goal you could say.
It seemed quite impossible as I come from a working class family however I decided to work during college in order to save every pennie and book a flight to the UK.
I was finally able to do it, I was one flight away from seeing London for the first time ever, I could not have been more excited.
Once I got there, for the first time in my life I knew how dissapointment felt like. It was nothing like I imagined, it was exactly how no one ever described it to me: crowded, dirty and ordinary.
I learned to love its streets and its people but frankly I'd only return if it was for free.
Hope this helps :)
