Missed

I'm eating, and while I'm eating, i can see a possible shape on the table opposite. I go on eating as though I hadn't noticed. But my gaze gets restless, like a disturbed mouse or insect. I go fetch my pen and a sheet of paper, and I sit down again, same place. But it's all gone. I had set out to draw and now I find myself writing I had set out to...etc. Was my getting up enough to disrupt this organised, accurate and rigid world of lines and proportions? The shape came back in the end, it did. Where from, I don't know. Too late anyway: drawing had left me just like the shape had disappeared from the table. And it will come back too eventually, but these two, the shape and my drawing urge, will probably never meet.
