My brother has Asperger's and has lots of anxiety issues ,it was very bad over the summer ,particularly at night ,but seems to have calmed down now .There is now an issue with downstairs neighbour he needs advice on .She is a middle aged neighbour women ,generally quiet looks after the place and says hello ,however when her boyfriend comes over they get drunk and playing music till 2/3 am and often end up shouting and swearing away at each other ,my brother gets very upset and anxious about this
it used to be just the odd time but now he comes over 3/4 days a week .I had a word with her a while ago about this and she was apologetic and said it would not happen again ,but sun and Mon night there was the same issues and my brother is getting very upset and anxious about things .Any ideas about how to deal with this and move things forward ,obviously I want to keep the peace between everyone ,but want to stop this behaviour soon as possible
