At the endocrinologist’s office while he studies a bone density report on me:

Dr F: Do you have any shooting pains down your legs?
Me: No.
Dr F: Maybe down the back. They would be strong, shooting pains.
Me: Um, no.
Dr F: Well, if you ever do, give this to your GP and he’ll know why.
Me: Great.
Dr F: But it’s completely unrelated to your condition.
Me: Ah.
