Famous quotes containing the words list of, list, allowed and/or characters:

    My list of things I never pictured myself saying when I pictured myself as a parent has grown over the years.
    Polly Berrien Berends (20th century)

    Do your children view themselves as successes or failures? Are they being encouraged to be inquisitive or passive? Are they afraid to challenge authority and to question assumptions? Do they feel comfortable adapting to change? Are they easily discouraged if they cannot arrive at a solution to a problem? The answers to those questions will give you a better appraisal of their education than any list of courses, grades, or test scores.
    Lawrence Kutner (20th century)

    A major misunderstanding of child rearing has been the idea that meeting a child’s needs is an end in itself, for the purpose of the child’s mental health. Mothers have not understood that this is but one step in social development, the goal of which is to help a child begin to consider others. As a result, they often have not considered their children but have instead allowed their children’s reality to take precedence, out of a fear of damaging them emotionally.
    Elaine Heffner (20th century)

    There are as many characters in men
    As there are shapes in nature.
    Ovid (Publius Ovidius Naso)
