It happens. Everything. It all happens. Somehow. Life happens. Death happens. Existence happens. Everyone sees at least portion of it happening. All around them. Stuff happening. Everything. That's why our perception on everything is always changing, always rearranging. Because we see stuff happening, we see new things, we're presented with new situations, and our own everything becomes bigger. It becomes everythingier. Our perception updates. Always. It's always updating. It's like it's in real time. All because everything is happening. Humans are creatures of change, you see. We change. We update as our perception updates as the surroundings around us change. We change. Our everything changes, and becomes a new everything. Until of course there is nothing. At that point our everything's nothing, and we leave the physical realm with our nothing, and we cease to exist... however my everything is not nothing yet and I plan to make contributions to other's everything until they too have nothing, filling their everything with pleasant memories and plenty of laughs, hopefully. A quote I like from The Fault In Our Stars would be "Some infinities are bigger than other infinities". For example, there is infinite numbers between 0 and 1. No, really! Draw a line, label one end 0 and the other end 1, and divide it in half. Good, now divide the halves in half. Now divide the halves of the halves in half. Amazing, now divide the halves of the halves of the halves in half. Good work, now divide the halves of the halves of the halves of the halves in half. Way to go, now continue. It'll just go on for infinity you know. There is infinite numbers between 0 and 1. Now get this; there is even more infiniteness between 0 and 2. Exciting, isn't it? What I'm trying to get at is some everythings are bigger than other everythings, and some people's everything means different things to other's everythings. And everything happens. And everything happening changes. And everything happening changes us. And that happens. And it all happens. And we can't stop everything from happening. Everything will happen. It is we who must learn to adapt to the happening of everything, because everything will not adapt to existence of us.
P.S. That got a little confusing for a second there... sorry.
