I'm neither delighting nor being paradoxical. It's not even a specialty. O.o
Consider this, for a moment... Most of the universe is unaccounted for. While they give it a name, they have been unable to find any evidence of whatever-it-is (referred to as dark matter) other than there having to be something because fundamental laws of physics and such can't explain why, for example, stars on the outskirts of galaxies don't move slower than those closer to the center, or, at that speed, get flung right out of the galaxy.
Either way, that option in the poll (which I chose), just means that I'm only saying that each individual can only really account for their own existence. It's an "I think, therefor I am" sort of deal. So, while I think I'm real, others will think that I'm not. Does it make sense now?
