“Often, when there is a conflict between parent and child, at its very hub is an expectation that the child should be acting differently. Sometimes these expectations run counter what is known about children’s growth. They stem from remembering oneself, but usually at a slightly older age.”
—Ellen Galinsky (20th century)
“I brush my hair,
waiting in the pain machine for my bones to get hard,
for the soft, soft bones that were laid apart
and were screwed together. They will knit.
And the other corpse, the fractured heart,
I feed it piecemeal, little chalice. I’m good to it.”
—Anne Sexton (1928–1974)
“Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
—Marshall McLuhan (1911–1980)
