It happens to be my MIL who does this to me, which is relevant because I find it hard to respond as I would if it were anyone else. Some examples:
Oh, back from your holiday, I bet you're gutted aren't you?
It's Sunday night, you must be dreading work tomorrow?
Your baby's crying, I bet you hate that sound don't you?
Not long now until the wedding, you must be so stressed!
etc etc etc etc etc etc etc
She is generally a lovely person, but she does have this annoying tendency to prattle and put words in my mouth. With anyone else I might give a sarcastic retort to shut them up but I don't want to say anything that might damage family relations, we have to see them all the time.
I would like to hear any ideas on handling this as I have another 30ish years of this to look forward to
