Go away !

There is a  single housefly
It tortures me ,
It disturbs me ,
While sleeping,
When I play chain reaction ,
When I play subway surf ,
While watching tv ,
While having coffee
It  keeps singing  !
And I feel to kill it.
I feel to cut its tongue
So that it doesn't sing la la ..
One day ,remember
I will kill you .
And you can never
Get into my house

Before I kill you
Run away !
