I believe there is such a thing as a dumb question. If I did not beleive in the really stupid question I would probably have an easier time answering them. In fact I think the idea of no dumb questions was invented as a way of brain washing us into keeping our mouths shut when someone asks a question that is so stupid there is no answer.
If you really do not believe there is such a thing as a dumb question please go to Quora and read up. Pick any topic I don’t think it matters. That isn’t to say that all of the questions are stupid just two thirds of them. I take some comfort in knowing that Quora is not just for Realtors, if it were it would be called Trulia voices.
