rowyn, my thoughts exactly. If anyone is ever concerned about the welfare of (or care arrangements for) a vulnerable elderly person, they should call Social Services and request that a check be made.
Our elderly neighbour, Frank, had two care visits daily. The first was to get him up, dressed and fed, the second, to get him fed, changed and back to bed. That was his miserable existence with no family visits.
One day, we heard him shouting as we passed but he didn't answer the door (we knew he could get about slowly) so we thought we'd have to call the police.
A neighbour's husband took a ladder and climbed in through an open upstairs window. No, he hadn't had a fall, his morning carer had left his walking stick upstairs!
