Difficult isn't it ! Both of my parents died before any of these problems fortunately ..but my OH is now 84 with vasculaire dementia and Parkinsons (both in early stages as yet !) I could never take him back to the UK ...he would be arrested ! Here we are fortunate not too many people understand him as he only speaks English ....if we are out, he will say 'Look at the size of her' when anyone large passes right by .......he is also derogatory about people of colour, 'foreigners' (I remind him we are foreigners here !)....swearing at people, etc etc ........it is somewhat embarrassing .....anyone who knows him takes no notice whatsoever, others I am always apologising to ! The local café owner, where we go a lot, knows him and is good with him they call each other names ! others ask me 'how is the cantankerous old b....r ?' I know it is going to get worse - now, if I ask him to be more thoughtful in what he says, he just shouts 'I will say what I want '.......maybe I should be looking to buy a purple coat with a red hat that doesn't go, and run my stick along the railings ......if you can't beat em you may as well join em !!
