- Check whether the written message contains private information before photographing or displaying it.
- Ask before sharing the sender’s words publicly. Store personal cards separately from albums intended for wider viewing.
A worked example
“I’d like to keep the card in my own box. If I post a photo, I’ll show only the illustration, after checking with you.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Do not assume a card sent to you was written for an audience. Its physical presence in your home does not make the contents public.
