Knock on the door last night , and I’m faced with a lady in her 70’s I’d guess, asking if I can move my car ( on my drive) so she can get through ! I told her that it’s just my garage and no way out. She seemed confused and lost , I asked where she wanted to go and she told me ( 2 streets away ) she had gotten lost on her way home ! I had to get her to follow me in my car back to her house ,She lives alone . Upon my return my wife said perhaps we should visit today to check she’s OK , or ask a neighbour if she needs checking on . My concern is that she seemed in no fit state to drive and was hopelessly lost and only 2 streets away from her road . I’d hate for her to cause a crash. Any advice ?
