Inside My Page

I am filling my page.
As I put the paper
Up to a lighted lamp
Though it's back is toward me,
I see all my mistakes.
When the light shines on them,
They can truly be seen.
It's hard for others to
See them from a distance
Without the lighted lamp.
What shows all my mistakes,
Is the liquid paper
Which I use trying to
Correct them, everyday.
