In the book HitchHikers Guide to the Galaxy, what are good examples of where the reader might feel curiosity and sympathy?

Thank you.

When did you really want to read the next page to see what happens?

When did you wish that the protagonist hadn't done that? Or when did you wish he knew more about the situations so that he could have avoided the result of his actions?

If you can't remember, go back and skim the end of the chapters to refresh your memory.
