you often feel someone is following you, you then install a surveillance camera in front of your house out of curiosity, at 11 pm you see a cctv camera

suddenly a man appears and looks at the cctv, you are shocked, the man has a mask on his face, the man writes something and leaves, puts a piece of paper on the outside door, once it is safe, you open the door and check the paper

(I'll pick you up) which makes you scared and enters the house
