Yikes! May I ask how this happened? We're you in the middle of the scene and the door opened?

I wouldn't be surprised if that was intentional. I've read several stories from women about hotel staff coming into their rooms without knocking. It happened to me. I was barely awake and I heard the door open and someone came into the room. No knock, which is what they're supposed to do. I said "hello?" and they quietly closed the door without a word. It was eerie. Usually, I put that latch over the door so it can't be opened but forgot that time. Now I don't forget!
