Which eye

I was listening to him just fine, until I realized I was looking at his left eye. It was blue, encased behind the one lens of his glasses, staring straight at me. I thought to myself, Can he tell I’m just looking at his one eye. So I switched and started looking at his right eye—also blue, also encased behind glass. Well this isn’t any better. Where am I supposed to look? Where was I looking before, when I was listening to him just fine. I was so worried about where I was looking, I wasn’t paying as much attention to what he was saying. So my cues were getting off. I started laughing, nodding, smiling, shrugging at the wrong moments. I kept searching all over his face for a place to unconsciously rest my eyes so that I could focus on what he was saying. Eventually, I must have found somewhere. Because I stopped thinking about it, and just listened.
