Ms Blueberry's original post was rather over-the-top, but nevertheless I don't think it's unreasonable to expect people to prevent their properties falling into complete decay. "not derelict"? Well it bloody looks it, and has done for at least 15 years. If I lived nearby it would bother me. And if I was the owner/tenant/landlord/greedyrelative/etc, I would be embarrassed. If it really is a penniless little old lady living there, then why not ask for some volunteers to tidy it up?
