After my morning of capturing bees, I spent the afternoon in the peach stand out on the highway, selling T. Ray’s peaches. It was the loneliest summer job a girl could have, stuck in a roadside hut with three walls and a flat tin roof.

I sat on a Coke crate and watched pickups zoom by till I was nearly poisoned with exhaust fumes and boredom. Thursday afternoon was usually a big peach day, with women getting ready for Sunday cobblers, but not a soul stopped.

T. Ray refused to let me bring books out here and read, and if I smuggled one out, say, Lost Horizon, stuck under my shirt, somebody, like Mrs. Watson from the next farm, would see him at church and say, “Saw your girl in the peach stand reading up a storm. You must be proud.” And he would half kill me.

What kind of person is against reading? I think he believed it would stir up ideas of college, which he thought was a waste of money for girls, even if they did, like me, score the highest number a human being can get on their verbal aptitude test. Math aptitude is another thing, but people aren’t meant to be overly bright in everything.
