It's really cool graffiti. A good job that deserves respect. I have no idea who this person is associated with little people, but judging by your assumption this is the author. We can assume that here it is implied that the author was captured by his work (or correctly to tell the characters of his work or story).
I never like school readings where we all had to believe someone's else explanations of what we've read.
This is the correct position. School programs often suppress individualism in people. When we get a certain opinion and are forced to believe that it is true, we lose interest in reasoning. Training begins with the fact that a person has an interest to get to the truth by their own strength and reasoning. A school program is designed to "memorize" the imposed truth. It's good or bad, it's not for me to decide, but in my opinion it makes people lazy and waiting for someone to tell where the truth is.
So put everything under doubt and think with your head. This is the best way to develop.
Thank you
