Watching Frozen. It's an accepted fact I'm sure that their parents were shit. Basically kept both girls captive for years, completely ruined their relationship with each other, taught Elsa to suppress her perfectly normal feelings when this is NOT what the trolls advised and then off they swan for a wedding for two weeks when the girls were still minors. They were both culpable in what happened to Elsa and Anna in adulthood.
But are there any worse ones out there?
