Going to the doctor is like talking to a three year old.  You have to repeat everything you say because you aren’t sure they are paying attention and once they do hear, you have to explain everything you said which is always met with “why?” or “how?” or “are you sure?”.  Yet doctors can randomly be insightful like children.  You never expect them to say anything useful but one day they do and then go back to their normal self right away as if it was nothing happened.
