Never use word Hate, use dislike.
Please you have to change your behavior.
She is your sister.
Do not hate her.
This is good for your mental health.
She may wants your company wants to play with you.
When you do not give attention and time to her
She does like this which you do not like.
Make her your friend.
Give her gifts, tell her stories.
We cannot change others.
We have to make changes in our self.
