A person feels shame because he is something wrong. We may feel guilty because we lied to our mother. We may feel shame because we are not the person our mother wanted us to be.”
—Lewis B. Smedes, U.S. psychologist, educator. Shame and Grace: Healing the Shame We Don’t Deserve, ch. 2, Harper (1993)
“An afternoon of nurses and rumours;
The provinces of his body revolted,
The squares of his mind were empty,
Silence invaded the suburbs,”
—W.H. (Wystan Hugh)
