title_body: Designing realistic pragmatics, particularly with respect to answering questions
upvoted_answer: Consider the following:
  &quot;I can't answer that.&quot;
  &quot;I'd rather not say.&quot;
  &quot;I don't understand the question.&quot;
  &quot;It's not that simple.&quot;
  &quot;It depends.&quot;
  All of these are examples of non-answers which, as far as I'm concerned, are not rude. So I see no problem with designing a language that just has a non-rude particle for any or all of those situations.
