... The casual butt rub...
@snip36 Well, it's a ghost that wants to see funny things happen and enjoys joyful things. So, when she didn't like it when she didn't get to talk to him, the ghost thought of getting rid of the sister to get things rolling back the way they should, but she then mentioned she wanted to get along... So, if the ghost were to get rid of the sister, she wouldn't be able to have as much fun as if they made friends with each other...
