I think aspects of this thread are sad. None of us know the background
of the OP and this kind of thinking illustrates a joyful level of
curiosity that could have been answered in a way that helps the
questioner and build a positive community (for Shane, Rob did answer it
and in way that is really quite deep, and thinking about how he
answered it will teach you something that is worth learning).
Calling a question "silly" demeans the questioner without understanding
where they are coming from.
