There are no words to describe just how many buttons this book pushes but suffice to say regardless of the final "if it feels good it must be okay" message that you come away with my very conservative upbringing still shouts no it is not. Young early twenties or not these characters are not adults by any stretch of the imagination, at least not very mature ones.
There were fun parts and a lot of actually wonderful insightful moments that kind of snuck up now and again, on the whole it was easy reading that will allow an outlet for fantasizing about what would really happen if one came across a naked hitchhiker.
