@Ludonaut worked for a billionaire once who was having a casual lunch conversation where he came out with, "My carbon footprint is second to none!", then paused, thinking, for a minute, then said, "Maybe that's not such a great thing..." before the conversation moved on
I don't explicitly remember if this is what triggered the comment or not, but I assume it was the second trip to space that really put him above all the other billionaires
anyway I think about that moment a lot
