The friend with messed up dating pool.

I had this childhood friend who has fucked up dating pool. And when I tell u it's fucked up, it is. So let me give u context alr.
This was like a long time ago when we're in 8th grade. She was like crying and all my other friends were comforting her. And I was like wt happened. She told me she was crying cuz she has to break up with her fucking UNCLE cuz her dad found out. My brain legit short Circuited for a moment after hearing the word uncle.. And after that she dated her teacher in high school. And she gives me all this tea with straight face as if it's normal.
I kinda pity her though, not sure if the whole dating part with her uncle was even mutual. Iam pretty sure her uncle was in like in his late 20's. Yea pdf spotted. Sighhhhh.i don't even know Wt advice do I even give to her. I once tried but she didn't like it and said she does not need sympathy and she isn't a victim or anything.
