Realms That Dont Overlap

So many things intermingle. We can find ourselves in some unknown place but have little things remind us of another time, or perhaps a person appears. It is just how things seem to work. Not much is truly isolated. And yet some things try and overlap and shouldnt. Sometimes there needs to be a divide. A line drawn. Not a line in the sand, those can too easily be washed away, or blown or walked over. A real line. One that separates objects. Similar to the supposed separation of church and state, although I dont believe those two can be truly divided.  I suppose I am just trying to say that sometime we need to recognize boundaries and what we have a say in, and sometimes that means holding our tongue. Realms arent always meant to overlap.
