Home alone…

you came home from walking around the park and you were so tired… when you went to your room you had a email on your computer… you checked it and it was your father Mr William: “son/daughter, i wont be home until 10… get some good rest for tonight… i will tuck you in when i come home…” you got off the computer and relaxed in your bed staring at the ceiling, but then you get a another email and it was from a unknown person saying “are u alone?”
