The age of twelve is remarkable. As childhood comes to its end, the twelve-year-old can feel accomplishment and mastery of many skills in jump rope, running, reading, arithmetic, high jumping, memorization, writing, logic, and reasoning. Just as the sense of mastery peaks, the child’s body begins to change. Though the first changes are invisible, the child feels them with a growing sense of alarm at what the changes might be.
For the following three to five years, the developing youth experiences the same rapid growth experienced by infants. Never again will the developing human being have to manage so much growth in a concentrated time. The child begins to experience expansion and hair growth in unusual places, changes in the voice and, most importantly, changes in thinking and reactions.
There is a dawning of the capacity of judgment in the child at age twelve. Suddenly the child can evaluate, contrast ideas and experiences, and think about things in a new and discerning ways. This new capacity needs exercise and children can be brilliant arguers at this age, It is difficult to win an argument with a twelve year old. Relentless energy and indefatigable focus are possible at this age as at no other.
The child has much to manage with all this growth. It is frightening to see the changes and wrangle with them. After experiencing the mastery of a few months before, the growing preteen often feels betrayed by the adults on which he or she has depended. They cannot believe that they are changing and so they think that their grown-ups must have changed and this can make them angry or mistrustful.
