I have seen some questions related to this topic and found the answers interesting. However I am curious with my situation if the responses would vary. My mother in law has dementia - her activities include shopping, drinking coffee, eating sweets, and smoking. However with smoking she flat out refuses to admit it. She only smokes indoors in bathrooms in her house, my house, restaurants, bowling alleys.... When you ask her not to smoke indoors - she looks at you indignantly and states she doesn’t smoke. My husband stated it’s my issue. If I want to confront her it’s up to me - i.e. if I want to call her a liar I can do that. As if he can’t smell the smoke. Every time she visits I spend 12 hours cleaning the bathroom that supposedly no one smoked in - just to try to get the smell out of my house. I don’t want to cause a scene - it is bad enough when we visit them - I just don’t want the smell in my house. Any thoughts?
