Dr Dave had slept with one of his patients & felt really guilty. no matter how much he tried, his sense of betrayal was overwhelming. But every once in a while he'd hear an internal reassuring voice say 'Dave don't worry about it. You aren't the first doctor to sleep with one of his patients and you won't be the last and your single, just let it go'. But invariably the other voice would bring him back to reality whispering 'Dave you're a f **kin vet!'
