Immediately, I was freaked out because he was so obviously high. He reeked off marijuana. His voice was shaky and he was studdering and not looking at my eyes when he spoke. I said, "I can't, I need to go to the ladies room.." So I walked (rather hastily) away towards the elevators, after I hit the button, I turned around and noticed he was still standing there, looking at me.
Then he started waving for me to 'come here' and I looked away. But I could tell he had started walking towards me. I jumped in the elevator and began jabbing the "Close Door" button completely scared.
So when I got to the first floor, I went to the Circulation/Reserve desk and told the student worker, "Okay, this is going to sound crazy, but I think there is a high homeless man on the third floor." I told him everything, and he just looked at me like I was a complete idiot and said, "Yeah, uhm. I'll go check on it."
Naturally, the second I left the library, I called UPD. They took an accurate description and called me back thirty minutes later to get my information for a report. And that was it. (They didn't find him).
So, the moral of the story is, there is a drug-induced psychotic bum lurking in our library. Just so you all know..
