I'm currently writing a story in a fictional diary format. This is proving challenging in several ways, but right now, my focus lies on trying not to give away any "big news" at the start of a diary entry.
From personal experience, when I write something in a diary, the most relevant information tends to come first, usually followed by an exclamation mark. (Examples: "I got the job!" "Sam has asked me out!" "We're moving to Sydney!") If I were to describe the same episode in standard prose, it would be easier to lead the reader up to this point without spoiling the surprise. But since a diary entry always takes place after the event, the main character is guaranteed to know the outcome, so what's to stop them from thinking (and writing) about it as soon as they sit down to write?
What techniques can I use to delay the reveal?
If it matters, the format I'm using is more a free-style journal than an actual diary. The character may sometimes skip a day (or week) and on other days may update their journal repeatedly.
I'm doing this as a writing exercise, so please refrain from the obvious, "Do something else instead". Also, I've already got a few ideas and will probably post an answer myself later-on.
