Such a sweet kind neighbour you are. Please do call social services. I once had this experience and i called my now partner, who was at that time a social worker. A lady was walking past my house and was very confused, she told me she was going to the dentist, but she had nothing with her to say she had an appointment, and she was resting her elbows on my front wall. I went out to her, she was so scared of me and flinched just as i walked towards her, this was clear to me someone had at some time in her life abused her. She came into my living room, i left the doors open so she felt safe, i made her a cup of tea and then got onto getting her some help. Thank god i did, her husband had died and her son was in Australia (lovely man) her daughter lived 3 miles away and never came to see her, and when she did, she was vile. Social services contacted her daughter and she was on holiday, not even mentioned it to the poor lady. Then they found a contact for the son and her son was stunned to hear what was going on and he came to see her after a few days. He helped her settle into the house, cleaned up for her, i got to know him, and when his sister came back she wasnt happy to see him. Obvious to him that she wanted all her mother had, and now he was back she was going to lose out. They even argued in front of this old lady and me when i had gone round with some casserole. It was later found that the daughter had lashed out at the women several times, hence why she was so frightened. She has since died. Her son sold her house and has gone back to australia. I always think about her and feel good that i made that call. You will too. xx (please excuse spelling, i am tired, but can't sleep)
