A couple of years ago I had a bit of a complicated and rare condition that required dental surgery (a tooth I broke as a kid caused some inflammation that basically dug a big hole in my skull over years) . The surgeon was so excited, especially when I opted for a more challenging and less destructive solution to the situation, I knew I was in good hands.

He was like "Ooh! we're going to have so much fun together! A case like this is soooo rare!" and I joked that it's not something you want to hear from a surgeon but it really assured me that he's good and passionate about his job. And he did indeed do a great job.
