I learned the hard way, never to correct my cousin, just change the subject. When she asks for something, I just say yes, and then she forgets, so not a problem.......yes works every time......when she was in hospital she asked for whisky.....first I said no.....but she kept asking......then I discovered and said yes, then she was ok......ps I did not bring whisky to hospital.....and she is not alcoholic I think she might remember it would make her feel better. But my saying yes also makes her feel better. I learned not to try to correct, just say yes.
