A loop is simply the beginning of a thought
Umm, actually, the completion of a thought

A loop is, i begin a story, i end a story
Umm, you know, we start talking about one thing, we finish it
What you find in humans is if you start opening a whole lot of loops
But never close any of them
And eventually the person just can't follow consciously
Because there's an old study that some of you may have heard of that says that human beings can process, and hold at memory at any given time
