I am fifteen and my sister is a year and a half younger than meShe seems to think she's older than me.it's annoying so I want to scare her really bad, or at least annoy her.
ideas - wrap everything in her room in wrapping paper, newspaper, or aluminum foil - fill her room with balloons- switch her drawers all around, so everything is put away, but nothing is where it should be -when she is sleeping, cover the floor of her room with plastic cups filled with water
