[~Misguided Ghosts~]

Absolutely deserved. My parents would have done a lot more than giving me work like that to do. ESPECIALLY if I was showing no remorse. You basically caused your sister a lot of excess anxiety and even trauma, which is not great. You might hate being locked up, but I bet your sister was in absolute terror being closed in her room with no way out. And what if there was some emergency such as a fire where she would have had to leave the house but couldn't because she was locked in her room? You can't say an emergency like that will never happen to you or your family. Try and think of things from your sister's perspective. Take one of your biggest fears and ask yourself what it would be like if someone forced you into that situation without consent.
