One can gain new insight from the strangest sources. I never knew how much could be surmised from looking at a photograph of you as a child.
I think back to one of myself at the same age, placed in a badly lit hallway in the house I grew up in; in which I sit, thin-eyed and wide-grinned, my fists curled up and supporting my chin. Aside from the blonde bangs and pink shorts, I don't think I look very different now.
I had to see you as a kid to be able to name those expressions I know as yours.
