Yes, I remember being clueless about a lot of stuff growing up, and asking why about these things. But adults tend to be too busy to answer why, or they assume it should be obvious, so they get annoyed, and won't answer the question, or will snap at you.
Of course it's obvious to them--they all ready know why! But those who don't have to blunder along completely clueless, until such time as we can figure it out on our own, either through brain storming, observation, or coming across enlightenment in something we read or see on TV/movies.
