Eye contact is hard, just sayin’
Sometimes I find it hard to look people in the eyes. Like right into their pupils. It takes a lot of focus and courage.
The picture on the bottom is a sketch of optic disks and maculas (the part of the retina with the best vision). It’s an intimate thing, projecting the image of another person’s eyeball onto your macula. If eye contact is good, I imagine the retinal vessels shaking hands.
