As a doctor, you have to learn to ask questions which in other (social) situations may otherwise be somewhat of a faux pas...
Examples include:
"How old are you?... Really!"
"Have you ever thought about killing yourself?"
"Have you ever tried to kill yourself and how?"
"Do you take illicit drugs? Or have you ever taken illicit drugs?"
"Do you hear or see things that other people may not see/hear?"

Today in I learnt a new one...
"Are you in any way related to your partner?"

Yes, today a lebanese couple brought in their baby who had a congenital eye condition. Causes are usually inherited and genetic.
Turns out the parents were first cousins. (!)
