When Princess Celestia assigned Twilight with a written report about Saddle-Arabian history, Twilight didn't think much of it. It should take her a couple of hours to read the book, and couple more to write the report.
Key word being should.
Now it's the middle of the night, she hasn't even started, and her nerves are getting the best of her.
May Celestia have mercy on her.
An ode to writer's block born out of frustration and anxiety.
