I saw the letter E, big, black and bold. Now read me line six, the nurse said, pointing to a row of blurry rectangles. I squinted and took my best educated guess, but the nurse frowned, scribbling a note on her clipboard. The second week of first grade, I had failed my first test. The school vision test was the one (and usually only) exam I failed each year. It became somewhat of a routine, seeing the school nurse, squinting at the fuzzy shapes on the eye chart, finding myself in the optometrist’s office a week later.
