The boy in the stripped striped pajamas  (Be careful.  There's a big difference between striped and stripped in English.  Naked people are stripped, threads on a bolt can be stripped, paint on a wall can be stripped in order to get it removed from the wall). (Pajamas can be striped, Zebras are striped, socks can be striped).

In the first chapter, the author introduces us to Bruno’s life. Bruno is a kid who lives very close to Berlin in a big house with so many rooms and a beautiful staircase. He mostly likes his life, he has three best friends “for life”, as he says , a lovely mother , and an important father who has a very relevant unknown job. He also has an elder sister, called Gretel, who is most of the time difficult to stand up to most of the time. One day, he finds his maid, María, packing his belongings, which is very strange because it only can mean that they are going to travel somewhere. Bruno talks with his mother, who explains to him that, unfortunately they are moving away. This is because of his father’s job. Bruno is confused, frustrated and sad, he feels like his whole life is being destroyed. In fact he is going to miss his mates and his grandparents as well.

Chapter 2 The New House.
The new house seems to be worse than Bruno expected it to be. He finds it cold, lonely and empty. Also the neighbourhood is quite sad too. There are no houses nearby like in Berlin, there aren´t any shops nor people talking in the streets neither. Bruno thinks that house will never be like home.This new building is smaller and not as cosy as his older one, however, he has more maids and a new chef whose outlook is not so good.
