Mother cannot let me finish more than a single sentence without interrupting. Usually to comment on something, anything, it reminds her of. Often leads to a long story that takes the conversation completely away from the subject under discussion. She is fiercely independent and controlling, but still asks my opinion and wants my input on absolutely everything. She does not have dementia, and often I need to reason with her on why a certain course needs to be taken. I take care of her business matters as well as many other things as her vision is extremely poor. If I make a suggestion or give an opinion without an explanation, her knee-jerk reaction is to disagree with me. But it is hard to use any experience, illustration, etc., to reason with her because I cannot keep the conversation going in a particular direction long enough to make a point. This has always been a problem, but is getting worse. Partly because I cannot stay focused with the constant interruption. I have BEGGED her to let me finish what I am saying. If I am reading a paragraph, I say , Please let me finish this before you comment. Doesn’t work. I have said “Please let me finish” so many times that now it just irritates her, and if I make any comment while she is talking (which is always), she snaps back, “let me finish, that is always what you are telling me”. She has this tendency with others, but nowhere to the extent she does it with me. How can I reason with her and keep my train of thought?
