I look people in the eye (anyway) - I am all about eye-contact and 表示中 I am attentive. I like the 回答 about such bliss that eyes are rolling back into their head! But I would THINK - maybe the person (though this sounds like a reference to a song または something) - would be because they are NOT that intimate, same reason I have heard about people who won't キッス while makinglove... I cannot fathom, I think that sucks and is sad. I think, sometimes, the eyes are a window to the soul.
