Jocy had a brief-but-unforgettable Forward to the Future spacetime slip. Her TWIDDER sports the special circumstance of having multiple witnesses! (See http://timeslipaccounts.blogspot.com/.)
A couple weeks ago, Jocy received an email from a friend along with an attachment of an essay. This friend wanted Jocy to read the essay before the friend submitted it to the professor. Jocy was discussing the essay with the friends currently around her at the time. She read through it, said (aloud) that it was fine, and that although the conclusion seemed rushed, she thought her friend could hand it in and get a decent grade.
A while after this happened, the writer of the essay arrived on the scene. She mentioned that she needed to finish her essay so she could send it to Jocy to proofread. Jocy informed her she had already read it. Her friend said she hadn’t even finished writing it, let alone sent it. When Jocy now looked on her phone for the essay, there was nothing. As you can see, Jocy had witnesses for this event.
