How do I proofread? Let me count the ways.
I proofread to the depth and breadth and height
My paper can reach, to make sure it’s right
For the ends of assignments and classes.
I proofread to the level of the perfectionist’s
Most basic need, by lamp and fluorescent-light.
I proofread freely, as students strive for Right;
I proofread purely, accomplishing my Best.
I proofread by reading out loud
So that my old mistakes will be laid to rest.
I proofread with an eye I seemed to lose
With my lost papers, --- I proofread with the eyes,
Mouth, ears, of all my life! --- and, if God choose,
I shall but proofread better after I come to the Writing Center.
