Try this
- Write what you remember and label it approximate if necessary. Ask whether the speaker wants to correct the words or leave them unrecorded.
- Confirm the intended audience, especially if you want to print or post the quote.
A worked example
“I remember you saying something like ‘let’s take the slow route.’ Is that how you remember it, and may I keep it under the photo?”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Do not present a paraphrase as a verbatim quotation. If the person declines, save your own observation about the moment instead of their words.
