Oh right, so it kind of goes with the job.  As a fellow medical professional, I can understand exactly why you have developed such a strong emotional reaction to your patients.  If I spent my working days staring into the bloodshot eyes of a bunch of sodden, lice-infested birds, it would probably drive me nuts as well.  The trick is not to let them get on top of you.  Try to liven things up with a few little games to amuse yourself.   Personally, I rather enjoy setting fire to my patients to see which ones scream the loudest.  Alternatively, I like to send them off for operations they don't need, or perform surprise amputations in the waiting room.  It's all just a bit of harmless fun and it helps to pass the day. 

Actually, if you like, why don't you bring some of your ducks round, and we can swap a few body parts?  Yes?  Oh well, it was just a thought.
