For a long time, I wouldn't look at other people when I talked. If I was called on in class, I'd look down at my paper a lot or something, as if I had the answer written down somewhere, like in notes or something. This was pretty convincing. I'd only really look up at the end of whatever I was saying. I used to be really bad about being turned perpendicular to the person I was talking to, and I would occasionally move my eyes over to look at them out of the corners. As I got older, I learned it was imperative to look others in the eye so that they knew you were paying attention. And if I wanted to get a job, I'd have to be good at it in an interview. So, I'm pretty good at it now, because I've trained myself. But if I'm looking at someone while they are explaining something at length, I start to freak out a little. Their eyeballs look like olives that jiggle around a lot. I fixate on them and it becomes harder to do the "Uh huhs" and smiles and nods. I do it, but not without effort. I have to keep my mind from focusing only on the eyeballs.
