it is not good when:

you are on call and it is 7:18 pm and you already want to go to bed because you are tired from getting not enough sleep and attempting to sleep in a zillion-degree room because your air conditioner broke but neither you nor your husband were able to stay home to get it fixed EVEN ON A SATURDAY because of work and due to these terrible sleeping conditions you are extremely tired and cranky and you’re not going to get to go home for like SEVENTEEN HOURS and this call thing is just so inhumane and also your throat hurts and one of your patients has herpangina.
