confusion...

My pal called " hai Zombie"
Me? I gazed, what?
Yes . he giggled.
Don't you know the meaning? he asked
Instantly i recollected and asked,
talking about 'UNIX' ? NO. he replied.
"That boy told me", pointing to a fair chubby guy he said
Iturned and looked at the guy
He was staring at the computer screen,
and his finger were dancing on the keyboard.
Me, a 'Zombie'?
I turned over the pages of oxford
And soon the word ' Zombie'
smiled at me , innocently
But seemed a disdainful smile.
Suddenly the lab instructor announced
' time over'
I shut down the computer and walked away..
like a Zombie.
