I was over at my friend Adam's tonight, and I mentioned that I've been recording a song about Batman having an existential crisis. Then Emily mentioned that that's pretty much what Batman is "all about." So I guess my idea wasn't very original, in the grand scheme of things.
And then I remembered that that's pretty much what having ideas is "all about," since there's been more than enough time for genuine originality to die in all of these years of humanity. So now I'm the one having an existential crisis. Again.
