My neighbor was a 60 something single lady who was going back to school and reinventing herself. She was gone most of the day but allowed her dog to roam all day. The dog thought my lawn was his toilet. I would come home from work, grab my shovel and start my evening routine of scouring for dog crap.
It tells me a lot about a person who let their "kids" crap on others lawns and not do or say anything about it.
