HI, I am worried about a neighbour. He was widowed years ago, retired a couple of years ago, has a son who lives hours away. He goes out once a day in his car to the local supermarket. His driving is erratic and worrying. He seems dazed and won't talk to any of us or accept any help. He seems to be going down the road my husband did before he was diagnosed with dementia. I don't know what to do about his driving. If I don't say anything and he has an accident I would feel that maybe I could have prevented it. His son can be contacted by another neighbour, and I don't know if I should ask her to do so. Or do I just leave it??
