Saints may always tell the truth, but for mortals living means lying. We
lie to protect our privacy ("No, I don't live around here"); to avoid
hurt feelings ("Friday is my study night"); to make others feel better
("Gee you've gotten skinny"); to avoid recriminations ("I only lost $10
at poker"); to prevent grief ("The doc says you're getting better"); to
maintain domestic tranquility ("She’s just a friend"); to avoid social
stigma ("I just haven't met the right woman"); for career advancement
("I'm sooo lucky to have a smart boss like you"); to avoid being lonely
("I love opera"); to eliminate a rival ("He has a boyfriend"); to
achieve an objective ("But I love you so much"); to defeat an objective
("I'm allergic to latex")
