I protested that only some people with asthma do better in dry climates, while others, like me, do better in wetter climates. She wasn't buying it.

Then she went on to argue with me that penicillin and amoxicillin aren't functionally equivalent for the treatment of strep. "You're getting penicillin. That's all we prescribe for strep." I told her I was pretty sure that the prescription would be for amoxicillin. "No, that's for something else. You're getting penicillin." Guess what I just brought home from Walgreen's: amoxicillin.
