In the book
the only alien on the planet by Kristen D. Randle (which by the way, very distinctly had a lower-cased title, and yet again I would love to discuss the symbolism and meaning behind that, but again, moving on), fear is a clearly defined theme that surges through the chapters of the story.
The plot is, to say the least, co plicated. Ginny starts her senior year and its all fun until she meets the lurking, lonesome boy in her class. His name is Smitty Tibbs (sort of), and he is a genius. He has never spoken one word in his life. Ginny crosses lines that really, shouldn't have been crossed and ends up tip-toeing through the unknown.
Ginny is afraid when she first sees Michael. Michael is terrified of his brother. Ginny is scared of what could happen to Michael. Caulder is sort of terrified of everything. I start to think about all the levels of fear, and if you can truly compare them because, with all honestly, everyone has their own fears for their own reasons. Some fear make sense to us like the dark or ghosts (both of which scare me). Others are, well... like I said, Everyone has their own reasons.
But then there is the actually question of what is fear. I define fear as the unknown. Simple and plain. The dictionary definition: Fear is a distressing emotion aroused by a perceived threat. Close enough. They both deal with uncertainty.
Ginny is uncertain about everything. College, school, life, her brothers, her friends. Then there is her math. Oh her math, the one thing that she could handle. She took her last problem to Michael because she knew he could show her how simple it was to fix. She knew he could settle at least some of the concerns she always had. She was quite selfish really.
Everyone is able to deal with fear in their own way. They have techniques they use to trick them selves that its OK. They understand their fear.
If you want to here something interesting, when I hear the word 'fear' I sort of picture a fluffy mass beside each person. This Fluffy mass varies from people, and is sort of like a pet. It stays close to you, but you are unaware of it until it jumps in your lap. I guess its hard to follow, but emotions can be like that sometimes.
