That was a joke. Let me tell you the reason why it is funny...
I just read a book about Stockholm Syndrome.
I just read a book about Stockholm Syndrome. It was pretty bad at first, but, by the end, I liked it.
This joke is definitional. Stockholm Syndrome is when a person is taken hostage, and begins to like the person that took them hostage. Apparently this person is experiencing the effects of Stockholm Syndrome in regards to the book.
