It can’t have been a bad time because he sent his own son to the same one.
Well, I went to Boarding School and wasn't abused but there's no way I would send my kids to BS. Learning to suppress your feelings, not being able to voice your concerns about anything or how to negotiate rather than living by a system of rules and punishments, missing out on how to parent your own children, not knowing being able to mix with your own siblings if they are in the same school because of the peer system or because they are in another school, etc, etc. Nope, I wouldn't send my children to BS having experienced the system and I think I was lucky because my Homelife would have been chaotic. There is such a large body of evidence to show how damaging it is that I couldn't disregard it.
