Book Girl Thoughts: Do you feel guilty not finishing a book?

A friend asked me that question, last night. Honestly I don't feel guilty when I don't finish reading a book. There have been some books I have read to the end that I thought weren't so good but if the book is really bad I will just stop reading it. It really sucks when a book starts out good but then turn into something really bad. That's the worst. I don't see why should I feel guilty when I stop reading a horrible book, I feel like life's too short to read poorly written books.

What about you, do you feel bad or guilty if you don't finish a book?
