What Makes the Ending of Paddy Clarke Ha Ha Ha so Powerful?

What makes the completion of paddy Clarke Ha Ha Ha so powerful? I think the destination of the novel is flourishing and very moving because it is what I had expected from the start of the breakup of paddys parents and the breakdown of paddy fields character. The polish of the novel is where the designer signals paddys emotions the most. The fight with Kevin shows an extreme change in what Paddy wants to be like and shows how much he wants to be feared and respected. The end of the novel, when Paddys da leaves home, was very reprehensible.I had thought throughout the support that maybe Paddys parents would have sorted things out. The author chose to show the breakup from Paddys perspective only making it harder for the indorser because we knew what was going to probably happen most of the way through the book. The ending I thought was particularly powerful as it showed the terror and personal self-doubt the Paddy was in directly subjected to. When I read the ending of the book, the first thing I thought afterwards was that it finished with no information about how Paddy, or any of the other family members, turned out.At first I was quite disappointed because I valued wanted to know if Paddy ever recovered from the state he was in at the end of the book, if he ever made friends with Charles Leavy or if Paddys ma found someone else. Then I accomplished that the book was not about what everybody was like and how they would end up, it was about the check and painful break up of Paddys parents break up Paddys emotions really get the better of him at the end. This makes the end of the novel more tragic and sad.The transformation in Paddys character really becomes apparent, when the fight between Paddy and Kevin happens. This is the time when he loses falsify and no longer realises the consequences of his actions. This made me feel very poor for Paddy and very sympathetic of his situation because he had obviously mortified down into such a state that he couldnt control his emotions or actions. All of these factors add up to, what I think is, a very powerful and moving ending to a very sad novel.
