I figured as much, typical when you want on! ENTJ hey places? I'll watch what I say then.
I agree, strong case for INTP, as he does talk like some of them. It definitely makes sense in how he gets caught up in the details and in minutia, as in his degree. At first glance, that's what I first thought, but at the margin. After digging into his life, I lean towards INFJ. He's far too eclectic to be another super thinker.
