It took me more than 30 years to manage it convincingly for anyone other than pets and intimates, and I still avoid it, because it usually either hurts or frightens me. I'll have to look at the other discussions to see how prevalent this is.
From a very young age, I could look my cats in the eyes for hours if there were hours available, and they could return my gaze. But when I looked into their eyes I saw love. When I looked into the eyes of my loved ones (human) I saw love. That is not at all what I see when I look in the eyes of most human beings - mostly what I see are little cold shiny marbles.
Edit in: and yeah, dealing with that definitely derails whatever train of thought I was on at the time.
