Try this
- Use a notebook or envelope that fits the privacy you want, and consider who normally uses the space.
- If the note is no longer needed, dispose of your own copy deliberately rather than leaving it among shared papers.
A worked example
“This is a private draft, so I’ll put it in my notebook rather than leave it under the grocery list.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
A label asking for privacy can communicate a preference but does not physically control access. Choose the storage arrangement accordingly.
