The dude intends to keep continuously moving from one place to another for the rest of his life, so he reckons he's extremely responsible by not having romantic relationships. Maybe he will even save money in some fund so that a contractor will move his grave from one graveyard to another periodically, after his death.
I'm just waiting to see whether that entire friend group would shame and convict the man after doing the deed, EVEN WHEN THEY FORCED THAT PROGRESSION TO BEGIN WITH.
I could totally see the sister being like that, even though she's the mastermind behind the scheme.
