Her stepsister was in disbelief and said she thought OP hated this pizza flavor.
OP enlightened her stepsister and said this variant was her favorite. Her stepsister protested, but OP feigned ignorance.
Later that night, her dad asked OP if she deliberately misled her stepsister about pizza. He said if that was the case, OP was wrong for setting up her stepsister.
OP asked her dad if he preferred if she missed dinner instead. He said OP should have talked to him instead of concocting a plan to trap her stepsister. OP felt she did nothing wrong.
Why did OP's parents not consult her about what kind of pizza she wanted?
OP's sister sounds like a chore to live with. Their parents can't blame OP for tricking her.
Why is OP's dad more upset that OP forced her sister to own up to her manipulations? Shouldn't he be more concerned that his kid attempts to make life as inconvenient as possible for her sibling?
OP's dad is too lazy to parent the kid who is causing the problem. OP shouldn't have to be more understanding because she's older.
It's easier for her dad to blame OP instead. He would rather target OP than face his parenting failures.
The parents should be more proactive in correcting their daughter's concerning behavior.
They know how she treats OP. Why would they let her choose OP's food on her behalf?
If her sister learned nothing from this experience, OP can handle the next sabotage this way.
It wasn't OP who tried to sabotage her sibling's dinner.
Their parents should stop enabling their daughter's childish treatment of OP.
If they don't, OP can also make them victims of her "pranks." Then OP could see how fast they would rectify the situation.
OP should not have been scolded for outsmarting her sister. She shouldn't have to skip meals and wait for her parents' lukewarm "punishments."
OP's parents need to sit their daughter down and get to the root of her issues with OP. None of what happened is OP's fault, and her parents need to step up instead of scolding OP for doing their job for them.
