This one’s anchor points are the ugly green plastic trash can that I roll to the road every couple of weeks and the pointy brick corner of the stoop. Its design is one long, looping strand ending in a bundle of filament that, at first glance, appears to be a miniature dandelion. It trembles the slightest bit as I bend over to examine it more closely, my breath a breeze that sends it swaying like a tiny trapeze.
