Hard times or chapter 4-6

I started to read the fourth chapter. But after two pages I notices, that I understood nothing, not because of the vocabulary... better explained: I read and I didn´t thought about the things i read about. My thoughts were going to my own relationship and so on. A catastrophy! :-) But now, I´ll try it a second time and I hope my thoughts will stay at the book...
In the fourth chapter the end of the relationship is described. Sam´s was bored with Alicia.

In the fifth chapter Sam´s going sicteen and Alicia is telling him, that he´ll be father.

In the chapter number six, there is a time, which will come a year later and Sam doesn´t know anything of the missed year. He suddenly has a baby, but he doesn´t know how to handle a baby...
He wants his old life back...
