My other next door neighbor, Hotpants, who's never done a lick of work herself (well, perhaps a lick) has her yard maintained by professional landscapers. Yesterday, they trimmed the ficus hedges, growing haphazardly, along our shared fence. Some - a lot - of trimmings fell into my yard and the workers left before I noticed. A bit irked, I couldn't bring myself to clean up Hotpants's mess, even though there was no one else to do it. Then, today, they came back for more trimming.
So, I went outside for a little talk, and politely pointed out what happened. Keep in mind, communicating with local laborers can be a challenge, since most speak limited English and I speak limited anything else.
"So," the man said. "You want me clean up for you?"
"I would appreciate it," I carefully urged, "if, in the future, perhaps your guys might be a bit more careful."
Not sure how that went over.
