My mum is 87. I have been dropping food round to her door and we have been in touch via video chat. She goes out each day for a short walk, usually around a green as this is quiet and opposite where she lives. She has asked if I can meet her to walk round the green with her (2 metres apart) but although it would be nice for her to have company, I don't think this is a good idea or allowed. What do others think ? Thanks.
