Seeing a Stranger

I had to run some errands today so I took the subway into town. On the way back, I was riding down the escalator when I caught a glimpse of this girl, riding up on the other side. First I glanced at her, and I noticed that she was pretty. But then there was something about her face that made me look again. She wasn't exceptionally pretty; I took note of her various imperfections, none particularly significant, but altogether making her objectively unexceptional looking. The thing was that she looked familiar somehow, although I couldn't place her. My first thought was that she must resemble some actress or other, although which one I couldn't decide. Then the more I stared at her, the more I noticed her look. She seemed to be looking off at nothing, noticing nothing, but her expression was certainly not vacant. Something about her eyes, which would not meet mine, pulled me in. I wanted to say something to her. I wanted her to clear things up, to explain herself, to help me figure out why her appearance had sent such a jolt through me on an otherwise uneventful commute. I would say, "You look like an actress," and she would say, "Oh, yeah. ____ ____, right? I get that a lot." Then we would smile and part ways. Or I would say, "Do I know you from somewhere?" to which she would reply with a quizzical look and say "I don't think so" or, "Oh, hey, Jo, yeah!" and a quick catch-up conversation would ensue, followed by empty promises to keep in touch. But I was going down, and she was on the other side of the escalator, going up, and anyway her eyes never met mine, so instead I just turned and stared at her as we drifted past each other.
