You think there is something going on at your neighbours. It has started to make you feel uncomfortable. Your DH/DP has told you to mind your own business, but your best friend says that you should start keeping a record in case something comes of it.
Write 5 entries in your diary of around 2-4 sentences each, recording what you've seen and what you think it might mean. Anything goes - don't worry about grammar, syntax etc etc.
