1st day back to High School

My first day back to high school for who i am is unlike who i was lolz.... I was alittle nevous but kinda feel alittle funny in thought as I walked to the class. I didn't actually know what I am suppose to do there. I am very new with the position I am taking. As I walk, many student look at me and kinda wondering where I would be. Finally, I came to room 17. Hum... the kids are very friendly, asking if I were their examinor and bla bla bla...
