Earlier Part of Work Today

Work today was fine.  It dragged a little at the beginning, but at one point I looked at the time and was like "It's 4:30?  When did that happen?"
When I got there, I discovered that someone had decorated the lobby for Christmas. It seems too early still for Christmas, though once I'm on break I'll probably get more into the spirit. It always seems as if the spirit hits me just as Christmas is over, which means maybe I need to start right after Halloween if I want to care on time. But after coming home today, I feel like I'm getting into the spirit of things a little bit more.
When I got to my cubicle, my chair was missing. I usually hang my coats on the back of the chair, and I was totally baffled. I went over to see Mark's office since I'm suppose to check in with him anyway. He wasn't there, but the chair in front of his computer looked suspicious. I went into the boss's office and found my three coworkers, probably having a meeting. I asked if I could borrow the extra chair in his office, and realizing that the chair he was sitting on was usually mine, said okay.
