I Hate my sister ? we always fight, what do i do ?

Peo into a bottle, every night when she falls asleep, pour the peo onto her, so she think she wet the bed.
Every night

After a week or so, start asking her whats up with all the sheet washing? don't come right out and say you know she wets the bed, this will make you look gulity, after a make sure you spread it around school.
she will eventually go live in a cave out of shame.
