one of the difficulties in making a socially normal amount of eye contact with people is that if it doesn't come naturally to you but you're willing to try, you can accidentally make a little too much eye contact and great, you just changed everyone's first impression of you from "unfriendly" to "might be planning to eat my bones"
no! come back! I don't eat anybody's bones! I was really just looking at your forehead anyway!
it's annoying how when you miscalibrate this you get people telling you you're "intense" "intimidating" "hostile" and other vague adjectives instead of "you've been staring unblinking at me for minutes on end like a monitor lizard and I need you to please stop"
