The Road

As soon as I opened the first page, I was really overwhelmed by the amount of words I couldn't understand. However as I read the book, I could understand more clearly even thought I still had parts I couldn't understand fully.
This book is mainly about the man and the boy who survived after the earth came to an end. This book starts as the man wakes in the woods in the dark. The man and the boy is planning to go South because the weather is getting cold. They are walking the road and they are the only people walking the road.
The man and the boy don't have names; the man is the man and the boy is the boy.
The world came to its end for unknown reasons and it seems like few years had passed since the disaster.
Somehow the man and the boy survived and they literally have each other to depend on.
The man seems to be the boy's father. The author keeps calling them the man and the boy and I'm quite confused if they are really related or they just found each other after the world ended. Whether they are related or not, the man seems to really love the boy. When the boy asks the man what he is going to do if the boy dies, the man says he is going to die too. I could feel sincerity coming from the man.
Also when the man gave the boy coca cola and cocoa, I thought it was a fatherly thing to do.
The boy seems to be too small to know what's really going around them and I wondered how the man feels. The writing style the author is using is very calm and it doesn't show much of emotions. So we can only guess what the man is feeling.
How would it feel to know that they might be the last human beings?
Despair? Anguish? Hopeless?

I also found it quite ironic that even though all the people are dead, the man and the boy still desperatly try to survive. I always thought communication and interaction between other people made human beings happy and content and the main goal of life is to become happy.
Are they happy? I don't know. Judging from this book I thought that it was their instincts that lead them to survive.

Maybe for them each other's presence is the main thing that keeps them alive.

This book left me with so many questions and uneasy feelings but I can't wait to read more and hopefully I will understand this book better.
