Famous quotes containing the words high and/or frequency:
“These high wild hills and rough uneven ways
Draws out our miles and makes them wearisome.”
—William Shakespeare (15641616)
“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)
