“The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.”
—Jean Marzollo (20th century)
“And they be these: the wood, the weed, the wag.
The wood is that which makes the gallow tree;
The weed is that which strings the hangman’s bag;”
—Sir Walter Raleigh (1552?–1618)
