Analysis Of Sheldon Cooper

Sheldon Lee Cooper is a very popular fictional character on the TV show The Big Bang Theory. He was raised in town named Galveston, Texas to his mother Mary and father George. He has an elder brother and a twin sister. His mother was an ardent supporter of Christianity and she inculcated her religious beliefs onto Sheldon from childhood time, which he rejected. Sheldon was brilliant and exceptional in his studies right from the childhood. He was often teased and bullied by children in his neighbourhood. His inclination towards science subject and his extraordinary brilliance towards subject matter paved the way towards his early college admit.

He will not let anybody in his room, has a roommate agreement that is the size of a novel.
Sheldon: This is the temperature you agreed to in the roommate agreement.
Leonard: Aw, screw the roommate agreement!

He is also having germ phobia and he is a super clean person. He will clean his head once he touched some dirty things and he use the air cleaner many times in a day. He had seen Penny’s dirty apartment one episode and had to break into her apartment to clean it just so he would be able to sleep at night. I believe that the strict control during the anal stage make him so organized and clean.
