Creepy Crawlie

I worked last night at the Community Center. All in all, it was a fairly boring night. One odd thing - a guy that had been in the library ended up moving to the lobby of the Community Center after the library closed. He had three different computers in various states of assembly that he set up on a table and said he was going to be working there for awhile. I have seen this guy once before, and my radar went crazy. I have no idea who he is, but I have that kind of gut feeling that he is dangerous. The last time I saw him, he wanted me to unlock the library because he had left his gloves in there and it was closed. I immediately told him I didn't have a key for the library and could not help him. The real reason I didn't help him out is that I did not feel safe going into the dark library with this person I didn't know. So - last night I was already leery of him, but the Hispanic soccer players were in the gym and I was not alone. That is, until they all left at 9:00 and then this spooky guy was the only person in the building with me. I was creeped out! I made sure I sat at a table with my back to the wall, because for some reason, I could see him coming up behind me with a mouse cord and choking me to death. I had even pre-dialed Jeff's phone number so that all I had to do was hit the Talk button if I felt threatened. (yeah - I know, but at least he could call 911 and tell them where I was; if you dial 911 on a cell phone, you get the nearest State Patrol office, which is in Owatonna). Anyway, he finally packed up his stuff and left, and I made sure to lock the doors right behind him. I don't want to go through that again! I could have called the police to do a walk through, but I figured since he was the only person in the building, it would look pretty obvious. But then again, I have always heard you should trust your gut instinct. Weird...
