Seriously, we think the guy does have mental health issues. His son does and is also registered blind (but can see). There is no wife - she left him which is when he moved here. His other adult children don't come near him and he never has any visitors apart from loads of builders, decorators, plumbers, electricians. He has torn up everything in the garden and turned it into a wasteland and erected warning notices about having security cameras!! We are waiting for barbed wire and a look out post to be erected!!
