On the one hand, there is an honest endeavor to seek more information about a particular question and being grateful for receiving that information (from a very likely reliable source) without drawing any conclusion as to the question's final resolution, but on the other hand, there is snark and completely baseless assumptions about a stranger's state of mind. Case definitely closed.
