i'm sure this has been covered here (as most everything has) but it hit home for me today. twice actually, once at a fast-food drive thru window and again with a cashier at a store. both times i suspected a few seconds into the interaction that i should rip myself out of my head long enough to look the other person in the eye. and both times i found them to be already looking at me expectantly, and then with what i perceived as relief when our eyes finally met. it struck me that eye contact may be more essential in faking normalcy than i had previously considered. i mean while technically not required in order to transact, lack of it seems to play into an almost instant judgement by others. anyone care to contribute experience or wisdom on this?
