And, hell yeah they are distant!!!
They, (he), likes to be alone a lot, or alone with people in the background, their acting as some kind of muzak-scenery for him.
I dunno, he's in his head a lot when he's both sedentary, and being active, or maybe not, I don't think he's thinking much when he's shooting skeet whereas he's certainly thinking, (I think), when he's climbing a mountain. :/
When I'm with him, however, he may be mentally distant, and certainly emotionally distant, at times, but generally speaking, he wants me by his side or in close proximity at all times.
And on a tangential note, I totally have to be all T-like when with him, he doesn't like to hear "gushy and half-assed" theoretical stuff/ideas about life and love.
