"That doesn't have to do with the story"

I am a little weary as to what Hemingway was thinking while writing this book. On the back cover it mentions how he was injured in Italy during WWI and then moved to Paris. It fails to mention if he was injured in the head, but I am going to venture off and say he was. Either that or he was completely shmamered while he wrote the text for the novel. Not only does he include words irrelevant to the book, but also comes out and tells his audience that. I am crunched for time people and I do not have time to read things that are not pertinent to the book as a whole. Oh yes, and mustn't I forget the paragraph-long sentence on page 103. Yes, I am all about sentence variation and using structures that best suit the point being made; however, this was a little over the top. Come on Hemingway, I do not need to know every detail that runs through Jake's head (although I could probably guess because most involve Bret). Okay, I am off my soapbox now!
