Obliterate

I grab the pink eraser,
Start with my toes,
Go up to my ankles,
Continue to my legs,
Ascend to my torso,
It’s all gone,
Don’t worry, it’s all gone,
I move along to my left arm,
I’m right-handed,
Resume to my chest,
And my lifeless face,
Now I erase it all,
“For big mistakes,”
My eraser says.
