Guilt and sense of betrayal!

All day long Bob had been feeling guilty. No matter how hard he tried he couldn't forget. The guilt and sense of betrayal overwhelmed him. Every once in a while though he could hear a quiet inner voice reassuring him, "Bob, don't worry about it. You are not the first doctor to sleep with one of your patients and you certainly won't be the last." She had such nice hair and she was very good looking.” Then, invariably though, another voice would bring him back to reality, "Bob, you are a `veterinarian."
