Helen Keller wrote her autobiography, The Story of My Life, because she wanted to share her story and motivate others. She knew her circumstances were unique and her challenges immense but she also knew that the "barriers" could "in time be swept away."(Ch 4)
There are many desperate moments in The Story of My Life as Helen must make sense of her "dayless" existence but fortunately, she has always been an inquisitive child and being blind and deaf does not change that. This does also increase her frustrations though as her angry outbursts occur frequently, "sometimes hourly." (Ch 3)
The garden then is a place of great comfort to Helen and she takes refuge there often. It helps her establish her independence and is also a place, "the paradise of my childhood" (ch 1) where Helen can "hide my hot face in the cool leaves and grass."(Ch 1) Helen knows that, with the arrival of Ann Sullivan who will "set my spirit free," no amount of hardship or "darkness that followed" can "wholly blot out" (ch1) what she has already been exposed to.
Helen is able to enjoy - like most children - simple pleasures and, along with her friend, Martha Washington who is the daughter of the family cook, "one of my greatest delights"(ch 2) is to hunt for guinea fowl eggs. Martha understands and accepts Helen and, with Helen's insistence, gives in so that Helen can have her way. This seals their friendship.
