Jamaica Kincaid said this quote
“ Out of the corner of one eye, I could see my mother. Out of the corner of the other eye, I could see her shadow on the wall, cast there by the lamplight. It was a big and solid shadow, and it looked so much like my mother that I became frightened. For I could not be sure whether for the rest of my life I would be able to tell when it was really my mother and when it was really her shadow standing between me and the rest of the world. ”
