dirty old men

At my MiL's first care home there was an 'incident' which caused some problems for the owners with the CQC. Not long afterwards the owners sold up (not as a direct result of the incident, but because they were struggling on a number of levels). We found a new home for MiL.
We discovered some time later, from someone who had worked there, what the incident was - a male resident had crept into one of the women's bedrooms and raped her. She was in her late 80s and utterly traumatised. From what I gather it's a common hazard, but care home owners and managers have a legal responsibility to ensure all the residents' safety. It's definitely not a role for the faint-hearted

I love hildaW approach, may be what he responds too.

You can't expect an 88 year old to have kept up with current attitudes, ethel, plus as Hilda and Luckygirl have said, he may be somewhat confused.

Dementia can make people disinhibited in all sort of ways, including sexually. He may not always have been like it. But you do need to tell him to stop of course.

No Ana this is not a wind up, I am really shocked at his behaviour. As I said I thought all this sort of stuff was forgotten along with the wolf whistles as I said before.

Yes - do it. Why are you asking what to do? - just tell him to desist.

Age has nothing to do with it. Once a nasty pervert....always a nasty pervert. He's probably always been like it. Also if he is tipping over into dementia that can make any tendencies more exaggerated.
I'd adopt a Joyce Grenvillel type voice and say....'We don't do that here William (his name), very loudly and clearly.

If I didn't know you as a regular poster, ethel, I'd have thought this was one of those school holiday wind-ups!

You're a grown woman, tell him in no uncertain terms to get lost. Loudly.
