Aged 11 I hated my teacher and keyed his car. As an adult I worried that this act meant I was a sociopath. Saw said teacher a few years ago in an airport having a go at his wife. Turns out he's still a massive twat and 11 year-old me was just an excellent judge of character.
@fesshole @blogdiva Kids often know. Students at a school I worked for ages ago got reprimanded for referring to a new, older, male hire as 'the paedo'. Three months later he was arrested for possession of CSAM and grooming.
The kids felt something was off long before the adults suspected anything.
