If someone thinks that it is SHAMEFUL or WEAK, here are some excuses you could use.
1. The book stunk. It was not worth it, not worth my time!
2. I had no time to read it and no time to complete it.
3. I will not force myself through awfulness, because reading is a happy thing that makes you feel emotions.
Though really, it is a waste. Think about it- a tree died for this book, and the book wasn't even worthy!
