No need to apologize. I just have a preference when it comes to my healthcare. Some people like the joking and light heartedness. But to me it comes off like I'm not being taken seriously. For instance when I went in for my molar prep after my root canal the dentist had to suck out the tooth plug before drilling. As it came out the straw it made a popping sound. He chuckled and said to his assistant that "that's so satisfying". I found that grossly inappropriate. My mouth is not your YouTube video.Your right. (Let me get that out there first. And it doesn't change!)
A lot of us try to lighten up the situation hoping to put the patient at ease. It doesn't work for everyone obviously. I try to assess that before I try but even then there are some fails.
I apologise on behalf of us jerks.
