This is more of a general suspension of disbelief issue, but when the author is clearly more sheltered than their own characters/written situations, such that the world they've built isn't something anyone would really be interested in and also the way the characters and react within that world arent really believable -- again, because the author hasn't either been through those emotions or lacks the empathetic imagination to write someone who has.

Tbf, haven't seen it too much, in professionally published works, but when I played editor for my peers in university... Holy shit.
