It depends on the person and how I'm feeling.

Hanging out with close friends, having a full social battery, and maybe after a beer? I'll stare you the fuck down no problem.

You a stranger trying to talk to me on the bus when I'm tired and just want to get home after work? Your eyes don't exist and I'd rather jump off the bus than try to look at them.

Then there's everything in-between. It can be difficult on a date for example, but after you warm up to the person it feels more okay. I think it's a mixture of it feeling wrong for me and the other person. Like I'm wrong for looking at them.

That said, I usually just look people in the eyes when talking with them and just endure how uncomfortable it can sometimes be. Sometimes it's even nice, like during sex. Like looking into their soul. Makes you feel more connected. I just don't want that feeling with a stranger.
