Something not to do

1. Work for a long time on a document, saving fairly infrequently.
2. Decide the document should have a different name, and instead of saving it again with that new name, move the original file to that location.
3. Open the file at the new location, electing not to save the changes.

Hope you're having a great morning doing today's work. I'll be here repeating yesterday afternoon, which I don't recall enjoying too much.
