He is 65. He often thinks I said something his way when in fact I said it a different way. He has in the past made inappropriate comments in public which has mortified me. He used to be a good car parker but now his spacial awareness is not good in that respect. There are a few things - I can’t put my finger on it but he acts in a very similar way to my mum when she had early symptoms of Alzheimer’s. Do you think it is anything to worry about or am I being paranoid?
