Address : being essentially private, diaries have no convention of address, but the best examples give a sense of the writer conversing with himself / herself ("As usual, I'm thinking of..."; "Why do I always...")
- Register : informality enriched with sophistication - since diaries are personal, some informality can be expected in register and rhetoric, but higher marks will go to exam scripts which combine colloquialism with dashes of complex phrasing and effects.
