I have no idea if there’s something wrong with her, but her parents are clearly nutbags.
Having known insane parents of normal children, I won’t be quick to side with the parents on this. And paying tuition or not, any parent that computer bugs a 21 year old deserves to be disowned, mocked and shunned.
When 18 year olds fight and die in war daily (and history shows responsibility at far earlier ages), no one will ever tell me that a 21 year old needs to be spied on for their own good and have me believe it.
