Time Slips

I had an interesting thing yesterday. I was in a factory doing some computer work (no that's NOT the interesting part) and had the strangest sensation of not being able to tell if it were day or night. I guess it was sort of like how people describe being in Vegas. It's a bright factory on the inside with no windows and I started looking around and began to question to myself if it was day or night outside. I had a clock, I knew what time it was, but it was so strange. I guess you might get used to working on that environment, but it did strike me as very unnerving. It was late afternoon, and had it been the winter time it could have been dark out, maybe that lead to some confusion, but still it was a strange feeling. Makes me like my office window even more.
