My dad and his sister live together and have done since their partners passes. The carers come in several times a day to see my aunty who is lovely. My dad is so rude to them. I think he may have early onset dementia. He told one lady she was fat and other she smelt. I'm concerned that the are going to stop coming because of this. I have tried to talk to him but he laughs and tells me they know he is joking. It is so embarrassing
