     “Good night, Yammine.”“Good night, Chief.” I reply.The cell door   1    and I hear Chief’s
keys clinking as other doors clang shut further down the row. I step into my little cell and sit
down. I glance up at the window, covered in mesh (铁网),and think to myself, “This isn’t
a life, it’s just a(n)   2   .”Being   3    makes me feel as though I’m being buried alive. I am a
puppet (木偶) with people   4   strings so that I eat, sleep and wake when they want me to.

learn and was   16   to realize my dream.Now, after five years’ persistence, heartache and hard
work, I have   17   my goal. Having   18   a course as a reading adviser, I can now help others to
read and write. And I have even started a creative writing workshop at Junee Correctional Centre.
Learning to read and write at a higher level has given me the inner strength to present myself in a
more   19   manner.And the day I’ve dreamed about has come true: I now enjoy my cup of coffee
with a book in my other hand. Learning to read and write has changed my life and this article is my
first piece of “proper” writing, and it won’t be my   20
