So last week Mintern was on a mini-vacation and I was by myself and having a rather stressful day. I got back to the library from running errands all over the facility and all I wanted to do was sit in my office and catalog in peace. I turned the lights off in the library to indicate that nobody was home and made my way to my office. As I was sitting down at my desk, I heard three quick knocks on my door and I glanced up to see who it was. (I thought it might be a staff member because I locked the door and had the lights off, but someone could still come in if they had keys.)
I saw what looked like a white face looking at me, and since I hadn't been too focused when I was glancing, I made a concerted effort to look at the door and say hi. However, when I moved my body enough to get a full-on view of the door NOBODY WAS THERE. I KNOW I heard the knocks though because frankly, I was annoyed to have to make polite conversation haha.
Library Ghost strikes again!
