Reverse Lock
It’s truly so sad to see how common it is for parents to lock their kids in their bedrooms. No matter how troublesome they are or how much they act out, there is no reason to treat your kid in this way. It is meant to be a house, not a prison. Unfortunately, this is still a very common practice in many households.
I hope that this realtor reported each of the parents to the police, as there’s no other reason to have reverse locks on the bedroom doors. It’s even worse knowing that some of the houses had them on the basements – locking your child somewhere spooky like this is utterly cruel.
