Any more questions ?

I always end all my consultations by asking my patients - "Do you have any more questions". Most say that they don't. And my reply is - "I worry when patients don't ask questions - no questions means you have not understood anything - or you've understood everything - and I can't give you a pop quiz to find out which is true !" I find this helps patients to ask questions and clear their doubts - so they don't need to call me at 10 pm !
