I am an eraser
You can call be rubber too
Don’t worry
I rub pencil marks
Not feelings
But
My life is decreasing
Slowly and gradually
I am vanishing
The more you make mistake
The more pain I face
Whether its artist
Who forgets to highlight pupil of eye
Or
When pupil write right instead of write
The more you buffer
The more I suffer
You sometime write
Practice as Practise
Advice as advise
Principal as principle
Except as expect
And I easily accept
To rub and be rugged
Even if I am half dead
I can erase with my edges
Most important to you
Earlier or later
I am your mighty eraser !
