- There is no word limit on the letter being written. Your challenge is to keep it interesting irrespective of how long it is.
- The letter should be written to a fictional character (from a book/movie/TV Series), not to a real person (alive or dead), not to a person you have imagined either.
- The letter should be from you to that fictional character, not from a third party. For example you should be writing to Juliet, not Romeo!
