Mum has recently moved to assisted living and her ex neighbour who is gossipy and didn’t want anything to do with mum when she was ill and having metal health issues has contacted her in her new home to tell her we are moving her car around, going to the house etc. Mum cannot drive due to stroke and would need to retest if she were to drive again, so we have had her car in a different location so as not to upset her. This being told about what is happening in her former home is upsetting mum. What do i say to this woman who is interfering and causing issues for myself and mum?
