I couldn't agree more, my grandad has Alzheimer's and he often forgets that my grandma is dead and says he wants to see her, we have given up trying to explain to him what's happened as it always causes heart ache for everyone so now people lie to him, which I hate to do.

I wish that we had thought of something this simple to distract him, some people may say it's unfair, but isn't 5 minutes of trickery worth sparing them the heart ache that their life has vanished behind them and they have the decrepit body of an 80 or 90 year old person?
