The most important day I remember in all my life is the one on which my teacher, Anne Mansfield Sullivan, came to me. I am fille
d with wonder when I consider the immeasurable contrasts between the two lives which it connects. It was the third of March, 1887, three months before I was seven years old. On the afternoon of that eventful day, I stood on the porch, dumb, expectant. I guessed vaguely from my mother's signs and from the hurrying to and fro in the house that something unusual was about to happen, so I went to the door and waited on the steps. I did not know what the future held of marvel or surprise for me.
