Why all the Sarcasm?

Why, I am asked - if that is someone cared enough to ask it - am I so sarcastic? But I'm not! Or maybe I suppose yes to some degree I am. To some considerable degree some might say. And so why, why so sarcastic - seeing as that was the question. Of course I know whatever answer I furnish will hardly be anything like the whole truth but even so maybe it's all, the sarcasm, for the sake of appearances. What appearances? My own. For how else am I to maintain my reality, the reality of its appearance, in the light of the present? In the presence of such a light I am forced to be a darkness, in opposition, otherwise, well, I'd be part of it, and to be part of such a light, would be  . . . . well, it would be hardly to be at all . . . Maybe the trick so, you might say, is not to be in its presence.

And but to add - I can't just give up the point - where would everyone be if someone switched off that light - the one I'm talking about, the light of the present? If some ungrateful someone or other throws for example a big ignorant stone at it . . .  splinters, screams, darkness, out with the light . . . Well maybe everyone could find somehow their way, stumbling, by the light of a cigarette lighter, a phone, torchlit, into another room, again brilliantly lit, with maybe even a chandelier hanging from the ceiling, and guards, well-dressed, protecting it. And now and onwards it transpires, however unlikely, noone throws anything - or if they do they miss. But in the end the light will still end up going out. It will, like all such lights, exhaust itself. Show me a light bulb that hasn't exhausted itself - though yes admittedly I'm talking about the used-up ones. But anyway, why not just change the bulb even if it does go out? Ah but that's not the point. What about for example the terrifying interval of darkness between bulbs - people, unable to see each other, might go mad. But at least they could hear each other - though with all the groans and screams they might be better off not. Still there'd be the occasional voice appealing for calm, though to be heard he'd have to shout presumably so loud, he probably wouldn't sound all that calm.

So, given all that, why not just go outside into the natural light and not have to be relying on any light bulbs? But wouldn't there still be the same need for sarcasm, you know, so as to exist, to maintain oneself, in opposition, so as not to be part of the light? But I think here is where darkness really would just be darkness, willful, stupid. What would be the point? And how long, even accepting all the stupidity, for that matter could such opposition maintain itself? If you took the light away from the darkness where would it be, left to itself?

Well I set out trying to clarify things, to be straightforward, but glancing back at what I've produced it seems it's beyond me. I drifted off it seems into God knows where.
