BULLYING

Annother possibility of symbolizm could be bullying.
"Marvin K. Mooney could you plase go now," could be the voice of mocking students, telling him that he is unloved and that nobody wants him.
Did Marvin K. Mooney ever do anything wrong? He's constantly being asked to leave with no reasons WHY. This is suffocating his human rights. Are they racist to purple-wearing midgets? What did he ever do to them? Also: how did Marvin. K. Mooney get there? What is he doing there? Why is he so stubborn and opposed to leaving?
Marvin K. Mooney clearly symbolizes the poor, misunderstood kid, in the back of your science class. The voices telling him to leave are discriminitory and are telling him to 'get out of their face.' Why? WHAT DID MARVIN K MOONEY DO AND WHY IS HE BEING PUNISHED?!
These are questions that leave me staring up at my ceiling in the late of night, wondering, trying to figure out what he possibly could've done to deserve such harsh treatment. Perhaps they were correct in their asking him to evacuate the premesis. Maybe they even asked him politely the first time.
We don't know. All we know is that Marvin K. Mooney must leave. Now.

The time has come.
The time is now.
Just go.
Go.
GO!
I don't care how.
Your can go by foot.
You can go by cow.
Marvin K. Mooney
will you
please go now!
-- Dr. Seuss.

I have written a scene of an unwanted teenage girl at a party, and it goes the following way:

When Stacey showed up at Jennifer's party, she was very excited. True, her and Jennifer had recently had a falling out, however, she was sure that she would be able to get in with no problems.
After all, Jen and I have, like, been best friends forever, like. Now's like the chance to patch it up.
Her first arrival at the party was fine, she got in surrounded by friends, and started dancing and drinking. [Apple juice, that is.]
Her dancing was cut short by annother beverage being poured on her head, and on her hair! Her precious hair she'd spent so long working on to achieve the perfect straight, shiny mirror-esque quality was now ruined!
Turning around, she saw Jennifer holding the cup - the cup that had ruined her hair and was now dripping onto her pink tank top.
"Like, ohmigosh!" Stacey screamed.
Jennifer stared at her. "Stacey Z. Jones, will you please go now..."

As you can see, this book symbolizes BRUTALILITY, DISCRIMINATION, and BULLYING.
... that is all.
