|Hi! I'm here to review your work!
First impressions: This is a funny little story to start with, it's a tad confusing. As you read, however, you start to get that that's the point, and things really start to clear up.
Overall impression: I like this. It's short, sweet, and speculative. It gives me "Toy Stories" vibes, almost, except its office supplies.
Errors?: None that I see :)
Characters: you have 4 characters, Stapler, Scissors, and Tape, as well as Dr. Thomas, and they're all distinctive and have clear personalities.
Plot: The plot is good, well written, and structured.
Questions about the piece?: what happens after he throws the trio in the trash? Are they ok? Does he start to realize something is off?
Great job, and keep writing!
