A doctor is meeting with a husband after examining his wife. The doctor tells him: "Your wife's diagnosis is uncertain. She either has Aids or she has Alzheimers."
The husband asks: "What should I do, doc?"
The doctor advises him: "Drive her five miles outside of town and drop her off. If she finds her way home, don't fuck her."
Dr. Dave slept with one of his patients and felt guilty all day long. No matter how much he tried to forget about it, he couldn't. The guilt and sense of betrayal was overwhelming. But every once in a while, he'd hear an internal voice that said, "Dave, don't worry about it. You aren't the first doctor to sleep with one of their patients, and you won't be the last. And you're single. Let it go."
But invariably, the another voice would bring him back to reality. "But Dave, you're a vet."
