Yeah, the thing is if we did bring them here, they wouldn't know anyone. Grandpa can't speak the language and nobody knows whether she suffered brain damage. Hell, not even Granny would be able to speak French now. We do have a first rate guest room, but Grandpa would get bored. There's nothing for him to do here. If they had their own house it would be rather ridiculous. There aren't any for sale near here and as you say if they can't live on their own in England, they can do it even less here. In a country in which they can't even speak the language! There'd be other complications as well. Getting a permanent living visa and everything. If they did went to your place, the climate would get to them. Look at what happened in 2003. The summer was EXTREMELY hot and many old people died through dehydration and heat stroke. At least they'd be able to speak with the people. Grandpa would be bored though. You see, they don't want to move. Grandpa has his friends there, even though Granny wouldn't care probably.
These are excuses, not good ones admittedly, but what can we do? If only Grandpa would accept help! Moving them is not an option, so help has to be brought to them somehow. I offered to give up Uni to look after them, since I failed everything anyway I could just as well be doing something productive. As you can see I started 2nd semester anyway...
Yes, my mother too seems to be taking it lightly. What I can say is: Person A is taken ill, Person A falls into a coma like state, Person A seems to recover and is lucid, next day Person A is dead. It's always like that! Someone seems to be getting better and the next day they "are no more".
