The Romance of a Plain Man by Ellen Glasgow

For the next two years, when my mother sent me on errands to McKenney's grocery store, or for a pitcher of milk to old Mrs. Triffit's, who kept a fascinating green parrot hanging under an arbour of musk cluster roses, it was my habit to run five or six blocks out of my way, and measure my growing height against the wall of the enchanted garden. On the worn bricks, unless they have crumbled away, there may still be seen the scratches from my penknife, by which I tried to persuade myself that each rapidly passing week marked a visible increase in my stature. Though I was a big boy for my age, the top of my straw-coloured hair reached barely halfway up the spiked wall; and standing on my tiptoes my hands still came far below the grim iron teeth at the top. Yet I continued to measure myself, week by week, against the barrier, until at last the zigzag scratches from my knife began to cover the bricks.

It was on a warm morning in spring during my ninth year, that, while I stood vigorously scraping the wall over my head, I heard a voice speaking in indignant tones at my back.
