I know this is probably a well-worn topic. But my father-in-law, who has dementia, has taken against my 18 year old daughter's first boyfriend - and we believe it's ethnicity which has caused him to do son. They met at a pre-Christmas family meal. Ever since then when the boyfriend's name has cropped up in conversation, my father-in-law has made the following comments. - My daughter could have done better - The boyfriend is rude - The boyfriend is dodgy. - There is something 'funny' about that boy - The boyfriend is villainous. - He, (my father-in-law) can tell this, because of his police background, although the rest of us my have been fooled by him. The young man in question is a well-mannered, hard-working person who plays a lot of support and is studying medicine at a well-regarded university. My daughter is enjoying his company, and the rest of us are happy to have him around. My husband is really annoyed by my father's behaviour!! Any thoughts?
