I was uncertain whether this post should have the title I gave it or “Till Gray Do Us Part”. I’ve chosen the standard formula to echo the Italian version: “Questi, che mai da me non fia diviso”. That is Dante’s Inferno, of course. But, really, I am going to discuss an aspect of Lab which is very well known but, I suspect, sometimes ill-understood. Moreover, I’ve drawn the conclusion that gray couldn’t really part anything, because it only represents equilibrium instead – but before you call 911 I suggest you to read on.
