Never ask a lawyer if it's OK to do something (it's always "no"). Ask them to explain the risks in doing so.

Never ask a programmer if something is possible (it's always "yes"). Ask them to explain what is involved doing something.

Never ask a doctor if something will make you better (it's always "maybe"). Ask them to explain the conditions under which a treatment/procedure will work and what could go wrong.

@davetron5000 Never ask an interpreter or translator how you say something in a language. The answer is "it depends on context". Give the situation, purpose and audience and you'll get an answer.
@DrInterpreter @davetron5000 As a sign language communicator, I've had to explain that so many times.
@darrenmorin @davetron5000 I work in French and it's common.
