I agree with Meeracat - a doctor who immediately makes a response like that is usually commenting on a bad situation that it obvious or apparent. As one who personally struggles with this issue - those doctors who are willing to tell me the truth are the ones who will come right to the point - even if it is not pleasant.I think the clue is found in the use of the phrase ". . .took one look at me".
We can just as well argue that since this is a retelling of the event that there is some room to question it's accuracy. One might exaggerate the situation in relating it for one purpose or another. I agree with Loob: a case has been made for either one.But it makes much more sense to notice a less amount with one look. this is the interesting one and worth saying, not the opposite.
