Use

my advantage
is the knowledge
That if you won't come in-
Handy
Hands will put you down.

It helps me realise
How to nock
As an instrument
functions for benefits.

My understanding
Bursts into the room:
the use
Is full
Im not useful

A salutary goodbye.
Im good at it
The fulfilment is mine.
At list im practical.
A good way to go.

You put me down
Let me shake your hand.

At list now
My body
Answers to faith,
My achievement is meant to be
My vanish.
