Then I looked around and noticed that everyone else was enjoying themselves at my expense. Worse, I was often a second-class citizen as my bicycle couldn't stand up to their cars.
So I said fuck it, bought a car, fly several times a year, use paper towels, drive to the air-conditioned gym so my body looks like it's useful, don't care about my waste as much. Can't beat 'em, join 'em. I still reckon I use and waste less than the average person (certainly less than the average American), though.
I can be happy with this because I'm not going to reproduce. I honestly don't care if humans die out a few generations after me. I used to care but I just don't think we are worth it any more.
