Chalk

Magnet waved to Ethel from across the street
He quite liked these new social distancing rules
He could pretend he wanted to speak to people
Ethel didn't much care for the new guidelines
Her frail legs burst into action as powdery hips crumbled around them
She spewed questions of children aunts, uncles, grans, and granddads
Magnet quickly pulled out his trusty chalk and drew a two metre radius around himself
