“What people don’t realize is that intimacy has its conventions as well as ordinary social intercourse. There are three cardinal rules—don’t take somebody else’s boyfriend unless you’ve been specifically invited to do so, don’t take a drink without being asked, and keep a scrupulous accounting in financial matters.”
—W.H. (Wystan Hugh)
“Those of us who were brought up as Christians and have lost our faith have retained the sense of sin without the saving belief in redemption. This poisons our thought and so paralyses us in action.”
