James in the box

I am a James in the box
4 sides, a roof and a floor
I won't escape until somebody knocks,
Everytime I do, I show a little more

I'm trapped in this world
sometimes it makes me feel sick
theres so much i don't do or say,
when I'm loosing my mind, theres only my box to grip

I'll never be rid of my box
It came one day, and never went away
It does protect me from all the mocks,
but stops me saying what I need to say

People question why I act like I do
"that James is so quiet and why?"
but I'm not quiet, if only you knew,
its the box that makes me so shy
