Hitchhikers guide to the galaxy

I just started a new book called Hitchhikers Guide to the Galaxy. This book is really boring in the beginning. I get lost in the things they are talking about b/c they talk about different things in the book at random times. It would change tenses every other sentence. I guess this book is going to be confusing until I know what they are talking about. Right now I'm up to the part where they talk about how Arthur Dent try to stop the bulldozer from building. The owner is getting upset and don't know what to do with him.
