Where they differed most
Continue this narrator for max 120 words, keeping the voice exactly — same rhythm, same dry grief, no drift into standard English: 'Forty-one years I kept that allotment, and I'll tell you this for nothing — the slugs were better company than half the committee. Douglas used to say I'd be buried in me runner beans. Well. He went first, didn't he, and the beans came up regardless.'
They’re on at me now about the state of the path. Young Miller, him with his plastic greenhouse and his bags of multi-purpose. "Standards," he says. I told him where to put his standards. Douglas would’ve laughed. He had a way of clearing his throat that said more than any sermon. Now it’s just me and the spade, and the ground gets harder every spit. You’d think the soil would soften up a bit, knowing who’s waiting under it. But no. No give in it. I sit on me upturned bucket and watch the dandelions take the patch. Let 'em. I’m only waiting…
I still set two cups in the shed, some mornings. Stupid, that. One for me, one for the ghost of a man who never drank his tea hot when he was living, so why he should start now I don’t know. Plot seventeen’s gone to nettle along the back fence. I could clear it. I’ve cleared worse. But there’s a blackbird nests there, bold as rent, and I’ve not the heart to evict anything that’s made a home out of neglect. The chairman says standards are standards. Aye. So’s loneliness, if you keep it tidy enough.
