A woman cogently arguing with no one

Just to list them: first a woman cogently arguing with no one, unless it was the toddler, who wasn't answering; second, a woman in a long-sleeved glittering top in the heat pulling along a young child who pulled along with him a flowering plant that was soon pulled out of the soil; third, an elderly golden retriever trailing a long black udder in the lawn.

Finally: when crossing the park, is it better to walk in the grey rut that everyone has worn in the grass or to walk, as I do for no clear reason, about a metre parallel?
