Three things your doctor needn't say:
1. "Your test results came back. They are the worst I have ever seen."
2. "So, you've been feeling a bit down... Y'know, sometimes people who take this medication commit suicide."
3. "Well, glad to see that things are still exciting!"
(Actually, Dr's O and S, I appreciate your over-sharing. And unintentional humour. Even if it sometimes scares the shit out of me.)
