Do you ever feel watched/listened to in your own home by DSC?

My DSD is 11 and has always since I've been in her life (5 years) listened to adult conversations, I don't know if this is normal but she takes a lot of pride in knowing exactly what's going on with our relationship and within the house in general and it's often made me self edit when she's here (40% of the time)
For example I might mention to my DH I need to book our dog in for a teeth clean and she'll ask the next time if rufus has had his teeth done, sounds innocent enough and maybe it is but when its frequent comments all through the day it does become wearing. I must also point out these often arnt family conversations, she over hears us talking whilst we cook dinner or load the dishwasher and she sits listening.
We were at a family party last weekend and my sister had a drink earlier to toast the occasion, small glass of fizz, when my sister got up to leave (bearing in mind this was around 3 hours later) dsd asked "are you driving? Just I saw you had a drink" tbh I didn't think much about it as I'm so used to these sorts of comments all the time but my sister was appalled and completely embarrassed in front of everyone, I do remember the room went quiet and I laughed it off by saying something like, are you the police?? DH said nothing
Anyway since my sister has pointed this out I do wonder if she should be called out on listening to grown up conversations and passing what feels very much like judgement?

My DSD used to do this around the same age. The more annoying element was the constant questioning trying to find out how much I earned. She even asked my adult DDs - and got short shrift from them to mind her own business.

We suspected her mum was behind this as the questions were posed using language a child wouldn’t use. At the time I wrote articles for a local newspaper and she kept asking how much I’d been paid for them (I wasn’t) and could I write for other newspapers or do other media appearances for money.

She eventually gave up thankfully.

Oh gosh thats so funny @MachineBee she has so obviously been groomed by her mum to ask that stuff I agree it isn't stuff a kid would normally ask.
