Trust your gut, always, even if it feels rude.
I was at a wedding being held at a hotel. I wanted to go back to my room, so I got on the elevator. A man jumped in with me at the last moment and got my attention.
I pretended not to notice. When I got to my floor, I got off, and he got off with me and walked behind me in the same direction.
I thought “Oh, don’t be silly, he is just a guest like you are”. When I got to my room, he paused, walked past me and stopped at the door next to mine, watching me.
I finally realized he probably was planning to push me into my room when I opened the door. Instead of fishing out my key, I knocked on the door and waited.
He also waited, pretending to fumble for a key. I knocked again, said “GEORGE? Are you still in there?”. I sighed and went back toward the elevator, and the man followed me back.
The doors opened, he got in, and I quickly backed out before the doors closed on him.
I reported him to the front desk. I think my quick thinking saved my life or at least saved me from being assaulted.
Trust your instincts. Always, always trust them.
