Uneasy recognition

I was at dinner last night with a couple of friends and a young lady sitting at a table opposite ours made eye contact with me a couple of times. It was almost as if we recognized each other but just couldn't place it. At least, that's how I feel about the whole thing. Over and over, we just kept studying each other's faces (somewhat covertly) and I felt like I could place her in a million situations that were all equally plausible and therefore equally unlikely. As she left, we locked eyes one last time and as she turned around, I felt like I had lost an old friend.
