Is it wrong if I want to kick my younger sister out of the family vacation?
Why would you kick your gounger sister out of the family vacation?
She always assumes a superior air and she never jokes with me except when other people are around.
You shouldn't do that, it would be wrong to kick out your younger sister. You should be more patient with your younger sister.
Fuck you, she drives me crazy. She does those things on purpose to annoy me.
While you are aware of your sister's actions, she may not be if she not very mature. Kicking her out of the family vacation would be wrong and cruel. It would be best for you to talk to her about her actions and how they make you feel.
