Read the excerpt from Story of My Life by Helen Keller. My aunt made me a big doll out of towels. It was the most comical shapeless thing, this improvised doll, with no nose, mouth, ears or eyes—nothing that even the imagination of a child could convert into a face. Curiously enough, the absence of eyes struck me more than all the other defects put together. I pointed this out to everybody with provoking persistency, but no one seemed equal to the task of providing the doll with eyes. A bright idea, however, shot into my mind, and the problem was solved. I tumbled off the seat and searched under it until I found my aunt's cape, which was trimmed with large beads. I pulled two beads off and indicated to her that I wanted her to sew them on my doll. She raised my hand to her eyes in a questioning way, and I nodded energetically. The beads were sewed in the right place and I could not contain myself for joy; but immediately I lost all interest in the doll.
