I regret it all. My whole life (not just mine but this whole existence) is a complete lie. I learned too late that there's no such things as gods and winged angels and demons. We are conditioned to believe it is our duty to get married and have kids and work fifty years, and join the military, and go to funerals, and celebrate stupid holidays...
The truth is, we pop into existence only to experience life for a few quick decades, and then die. Not just die, but we get deleted. A hundred years from the day we die there will be nobody left on the planet that ever knew us. Our names won't even come up in a dinner conversation. This life is utterly meaningless, but if there were a purpose it would be to enjoy the hell out of this ride. That's it.
