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 filled 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.

Explanation:

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 filled 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.

Miss Sullivan would repeatedly write words on Helen's palm with a demonstration to make her understand what was written on her palm but Helen did not understand as she thought it was just a game.

Miss Sullivan, for instance, would hand over a doll to Helen and write the word doll on her palm, in a motion. Helen amused, and repeated the demonstration with her mother's palm, still could not make any connection between the word,  and the object.  And this continued for weeks until one day, at the pump, Sullivan held Helen's hand under the pump as she spelled the word, "Water".

That moment was significant in Helen's life as she was able to make a connection between the word and the water as it flowed on her palm.

It transformed her life for the best. Immediately, she could communicate and no longer had to live in isolation.
