The Swimmer by John Cheever

I liked this story because it has a lot  of interesting symbols like the pools and the passing seasons, if you understand these symbols it will be easier to understand the story. 
Ned seems to have a perfect life, at least that is what he thinks, but as he travels pool by pool, he feels lonly because most of his friends disappear, even his family dissappears in the end of the story. This is a way to tell that you have to take care of what you have. Also every time he goes into another house or pool, you know something about his past, mostly bad things, since he rejects those things. As this happens he begins to feel older and with no condition. 
About the seasons, this guy believes that everything happened in 1 day, but actually everything happened in one year. It begins like a beautiful dream in spring and ends in a horrible nightmare in winter when he sees he is all alone. At the end is when he realizes everything that has happened; as if each pool represented a moment in his life. 

Mexico City Blues - 127th Chorus by Jack Kerouac

Nobody knows the other side

of my house,

My corner where I was born,

dusty guitars

Of my tired little street where

with little feet

I beetled and I wheedled

with my sisters

And waited for afternoon sunfall

When I read the beggining of the chorus it makes me think of the childhood of a person, but it can be a sad or poor childhood as it says "nobody knows the other side of my house, my corner where I was born". Maybe it is a secret or something nobody could have ever imagined, he could have been born in a difficult situation. 

                                               And ma's to bring me back  

to supper mainline


Hum washing line tortillas
and beans,
That Honey Pure land,
of Mominu,


Where I lived a myriad
 kotis of millions
Of incalculable
be-aeons ago


When white while joyous
was also
Center of lake of light

In Vain by Jack Kerouac

I think this poem has different ways to undestand it, that's why I think it is quite hard to explain. 
First of all it repeats a lot the phrase "in vain" every time it says something before... 

The stars in the sky

In vain

The tragedy of Hamlet

In vain

I believe that what the author wants to say is something like "anything in life is not worth it", or also it can be something like "everything that has happened for what?" 

Abraham Lincoln 

In vain

The Aztec empire

In vain

It is even more difficult to know what the author wants to say because it mentions a lot of different things, in nature, art, and history. When I read the parts about history I think that the author is saying that in the end all those fights and time of government was for nothing because society forgets about things, what also makes me think of ignorance.
