Some of the posts on MN (and yes I am aware it’s not necessarily representative of real life) by parents talk about their children’s’ lives in such anxious, involved detail. I’m sure they have their reasons.
Not tiny children, where obviously this is entirely appropriate, but secondary school age, and sometimes older!
I’m quite prepared to be told that I just had a weird upbringing, but my parents didn’t know the ins and outs of every friendship, drama, argument, feeling or even get involved in my homework, exams or extracurriculars. I’m closer with my mum by a long way and she certainly knew who my friends were etc. or if there was a significant issue, but I can’t in a million years imagine her posting on a forum agonising about, for example, my social circle or (!) my university workload. I still did well at school and got a 2:1 in a science degree. I think the space to increasingly have your own life at the teen stage is healthy, and certainly beyond this age.
I’m not here to bash concerned parents, but I wonder if anyone else thinks similarly, even if from time to time? Again, I think my own parents could have been a bit more involved, and this post is probably driven a lot by my own 
feelings about it all. Also have to acknowledge that times change but still this surprise lingers when I read these posts.
