A few days before Easter, my husband and I took Mom out shopping and helped her pick out 3 1 lb chocolate Easter bunnies - one for each of her great-grandchildren. At Christmas we had helped her pick out gifts for them, but by Christmas morning, she couldn't understand why they were thanking her for things she never remembered seeing before.
We thought we'd prevent that at Easter by "hiding" the Easter rabbits in her refrigerator and get them when we picked her up that morning so she could give them directly to them. (Many of you already know where this is going...) When we opened her refrigerator Easter morning, there was just one bunny head left. She'd eaten 2 1/2 lbs of chocolate in less than 48 hours. All by herself.
I asked her what happened and she said that she had no idea why she had bought so much chocolate, but she was almost done with it and was pretty tired of chocolate.
We have a saying around here "Dementia Always Wins". No matter how hard we try, dementia always gets the upper hand.
