We all carry our childhood with us throughout our life...some things are buried deeply...some things we take out to remember frequently...Paula was a survivor, a chameleon...she learned to create new personas that fit the changing circumstances of her life by watching her mother react to life...I thought the author did an excellent job of contrasting Paula and Julian in light of their very different childhood experiences...Paula was a closed up prickly cactus...a dessert survivor... all hard, sharp edges that protected the true inner core of her...Julian was an open succulent...soft, sensitive to his nurturing environment...accepting and giving... like plants and animals, human beings adapt to their environment and when are we most open to learning?...as young children...we are sponges in childhood ... for both positive and negative life lessons...
