How much does your parents understand you vs how much do you understand your parents? If you have children: How much do you understand your children, do you think they understand you?

I mean like, actually understand beyond just exchanging a few words a day. Like knowing hobbies, favorite foods, political opinions, favorite tv/movie/youtube channels/music/genre of entertainment, etc... overall likes and dislikes... you know what I mean...

As to why I'm asking: I feel like my family is just a bunch of strangers sometimes...

I feel like nobody really understands me.
