"Some things are better to ignore than realize" is a saying that many people tell us when we get too curious or anxious about something. Arthur here, heeded those words and started to accept the current situation......except reality didn't let him.
Arthur meets a girl that he never met before, but definitely someone of his dreams. He meets her randomly from a store where they both have the same memory of the earth being blown up into a million pieces. He dates with her and has a life that seemed to possible only in his dreams. However, one day when he came back home....he meets a familiar yet wannabe-not-familiar face in his house: Ford Prefect. At once, reality slaps him back all the way back through his formatted memories to his fears and reality itself. Arthur tries to act as if Ford wasn't really an alien, but a human that was his friend for a long time....but he gives up in the end. Humans seem to be infinitely powerless sometimes from the fact that they have to accept reality and that reality doesn't give you enough time to forget about it. I believe that many have tried, but in the end it came back to them.
This part of the book is basically the part where reality slaps Arthur back into place and his dream life ends with a short "splut." One thing I like about this part was that the author put in so many normal experiences that we don't care about and displays it as something special. Like the way Arthur meets reality again and the fact that his dreams can't last too long. We wish for things in our lives and parts of it come true, but the parts we hate the most still hover above our heads for no reason. They haunt you at times, but we deal with it; "we talk to our hearts" as the book
