““August 21. ... I've become pretty good at telling weeds fom not-weeds. But every once in a while I have my doubts. I come across an especially difficult root. I pull and it doesn't come out. I pull again. It resists. I dig my gloved fingers into the soil and grab it with both hands and pull yet again. It begins to come out, but I can see it's going to take several more hard pulls. And that's when the doubts begin. I begin to wonder: Have I made a mistake? Is this really a weed? If it's not supposed to be here, why is it resisting so? But it's too late now. There's nothing to do with a plant half pulled but to go all the way. And so I tug some more, and finally, shedding clods of dirt and worms, it breaks free of the earth---and I try not to hear the tiny, anguished cry.””
