behind the door

Hi, I'm a younger sister to, and I love scaring/pranking my older sister!!! So what I did last night was, I got all dressed up in a clown suit, with makeup and everything, and while my sister was buzy, I went in her room, and hide behind her door. When she comes in the room, slowly make noise like a scratch noise against the wall or something. When she gets suspicious, push the door open and make the scariest face ever! It helps if u have creepy music that isn't to loud. U can also hide in the closet. Make sure u run from her after cause my sister was screaming like crazy!! She was terrified. Make sure that ur sister is afraid of clowns cause that will help.
