But I haven't finished with the young lady yet. I had no sooner said what I have said and was just about to turn my eyes away and forget all about her, when, in response to some remarks of her aged companion, she laughed, and in laughing so great a change came into her face that it was as if she had been transformed into another being. It was like a sudden breath of wind and a sunbeam falling on the still cold surface of a woodland pool. The eyes, icily cold a moment before, had warm sunlight in them, and the half-parted lips with a flash of white teeth between them had gotten a new beauty; and most remarkable of all was a dimple which appeared and in its swift motions seemed to have a life of its own, flitting about the corner of the mouth, then further away to the middle of the cheek and back again. A dimple that had a story to tell. For dimples, too, like a delicate, mobile mouth, and even like eyes, have a character of their own. And no sooner had I seen that sudden change in the expression, and especially the dimple, than I knew the face; it was a face I was familiar with and was like no other face in the world, yet I could not say who she was nor where and when I had known her! Then, when the smile faded and the dimple vanished, she was a stranger again--the pretty young person with the shallow brain that I did not like! Naturally my mind worried itself with this puzzle of a being with two distinct expressions, one strange to me, the other familiar, and it went on worrying me all that day until I could stand it no longer, and to get rid of the matter, I set up the theory (which didn't quite convince me) that the momentary expression I had seen was like an expression in some one I had known in the far past. But after dismissing the subject in that way, the subconscious mind was still no doubt working at it, for two days later it all at once flashed into my mind that my mysterious young lady was no other than the little Lillian I had known so well eight years before! She was ten years old when I first knew her, and I was quite intimately acquainted with her for a little over a year, and greatly admired her for her beauty and charm, especially when she smiled and that dimple flew about the corner of her mouth like a twilight moth vaguely fluttering at the rim of a red flower. But alas! her charm was waning: she was surrounded by relations who adored her, and was intensely self-conscious, so that when after a year her people moved to a new district, I was not sorry to break the connection, and to forget all about her.
