I see it all the time. Not uncommon to see the carpet disintegrated also.

few times a week, high UV on wool or early generation nylon on north facing side of house

(south facing for most y'all!)

You have lived the good life for too long. I see this everyday. And people say you can't relate to real cleaners. Hogwash I say.

Well I guess I'm blessed...

Still see here in the sunshine state but not as much with the newer types of carpets.

Gotta love when the vertical blinds cause the carpet to wear down to the backing.
