Closed doors give the impression of secrecy. But what are these hidden secrets?   A lot could be happening behind closed doors: a couple could be cuddling, a baby could be sleeping, a boy could be playing, a girl could be reading- anything.  Behind a dark door could be a room bathed in light, while behind a bright door could be a devil's hell. Countless memories, thoughts, and feelings could be tied to what's behind just one door.   You never know, do you?
