Once, I was going to Starbucks, you know just getting a latte. So, after I got it and sat down and started working on my S.A then, I felt like something was brushing my back it was so weird so I turned around as quick as i could and nothing was there. So, I just thought someone opened the door and than a breeze came through. Then, I continued writing my S.A and everything was normal but then I freaked because i felt like somone was actually hurting me by slapping my head. So I screamed and everyone stared at me like I was absolutely crazy.
