Famous quotes containing the word shift:

    The frantic search of five-year-olds for friends can thus be seen to forecast the beginnings of a basic shift in the parent-child relationship, a shift which will occur gradually over many long years, and in which a child needs not only the support of child allies engaged in the same struggle but also the understanding of his parents.
