It's not a 'where' ... it's a 'with.' They are visibly AT HOME in the embrace of the other. It's visible and apparent that the comfort they find in each other causes those tiny aches and pains to evaporate, that tension in the stomach disappears, the air smells fresher and fills the lungs better... and ... just for a moment or two ... the rest of the world doesn't matter ... because everything is here ... and now.
It can't be faked.
It can't be bottled.
It's the closest thing to 'magic' anyone has ever found.
