Fuck a Duck?

"If a man says 'no' to sex, it's because he misunderstood the question."
There've been plenty of times when The Chemical Buddha thought he was being asked if he wanted to fuck only to learn he misunderstood. Sometimes, he'd awkwardly pull his pants back up. Other times he’d just leave them down and see if anyone else wanted something from 'the meat department.' His over reaction was the result of a scaring incident where his date actually asked him if he wanted to fuck. But he thought she said, 'Do you want the duck?" and he had already settled on the lamb. From then on, just to be safe, The Chemical Buddha started saying, “Yes,” to everything. Which resulted in him helping people move, watching his friend's incontinent dog, as well as attending several Amway and Mary Kay meetings.
Do you hear what you want to hear or what is really being said?
What is the cost of saying, "Yes," (when you really want to say, "No") in your life? How might occasionally saying "No," even to people you care about, make your life less complicated?
