Memory Loss

I wanted so much to remember --
The shape of the face, the eyes....
Eyes, the color of the softest, mid-morning sky on a cloudless day.
My mind tells me what to remember, but only in words.
The image fades like a white lily in the August heat.
I remember the voice, the conversations, the mannerisms, the tall, thin body...
The face is a blur.

Why does my memory lose the sharpness of images that I want so much to keep?
And the images that I want most to forget are etched onto my mind's walls, never fading, permanently residing .
