I think it’s a very deep statement (sorry to be cliche). Life is full of circles that overlap in some places, and each person is part of their own. But when we meet someone new, it changes us and gives us new perspectives, shaping who we are. I think that these words are true because when something ends, the world is left without it, just as it was before it came to be. Completeing it’s circle. For example, when someone dies, all the ideas they never shared are forgotten with them, so the world is left the way it was before they were born. I guess it just goes to show how life will go on.
