We all make mistakes....
This is short, because it it time to be festive!
Scenario: Lady comes in with abdo pain. I examine her and, in the spirit of Finals, I asked "oh, is that a scar? Have you had any surgery recently?"
To which she replied: "no dear, that's a stretchmark". Luckily she found the funny side of it, and in my defence, it was a very odd place for a stretchmark!
