In my department, we aren't allowed to do costumes. I had to work late shift on Halloween though, so after much twisting of my supervisor's arm, here is my costume - I was a pretty pretty princess. An old bridesmaid dress, a costume jewelry ring, and the crown from the game Pretty Pretty Princess. The deal was that I could only wear the crown after everyone left but the late team.
Nathan's workplace (ebay) was a different story entirely. When I stopped by to visit that morning, they were in the middle of taking team pictures. Each row of cubicles had decorated with a different theme and a lot of people had planned their costumes around that theme. Nathan's theme was pirates. They didn't do too much, but here's a sign by Nathan's desk. He had a cauldron of gold coins on his desk.
Another theme - The Nightmare Before Christmas
We couldn't figure out this row's theme - it just seemed to be generally creepy.
And finally the spider area.
It was hard to believe it was a business with all these decorations!
