Deadlines. I hate deadlines. It doesn't help when I have to work at Saturday. I hate Saturdays too.
This is my office, my room. I share it with one collegue, she could see me sitting there from that point of view.
Mouse.. I had to bring in my own mouse because the Agency couldn't give me a new one when the old one died. Papers, files more papers. Ringing phone - all because it is a deadline.
I know it is not the end of the world, but I still have day-off from the last year, and I have owerhours enough for a week. I am tired like hell.
TLDR:
Office wolf is not amused by Saturday-work.
