The travelling diary and the later account
Source A: an original imagined statement by a traveller who writes brief notes during a journey.
I keep short notes because an evening can erase the small distinctions between one afternoon and another. I record a phrase, an unexpected delay or the shape of a room before the next place gives me something else to remember.
The notebook is not a complete account. A hurried line may preserve an irritation more strongly than the kindness which followed it. When I write later, I need to recognise that the person with the pen was tired, pleased or impatient, not a neutral instrument carrying the day onto paper.
Still, I would rather have those particular marks to question than rely on a memory which has already made the journey into a story. Notes give later judgement something to return to, including evidence that my first explanation was too confident.
Source B: an original imagined reflection by a traveller who generally writes after returning home.
I prefer not to stop every interesting conversation to prepare its future appearance in a notebook. The wish to keep an encounter can become another way of standing outside it. Sometimes I understand more by allowing the moment to continue without deciding which sentence I will take away.
Writing later has limits. A precise phrase may be lost, and memory can arrange events too neatly. I do not pretend otherwise. I can describe an impression honestly as an impression, check what can be checked and leave an uncertain detail uncertain.
For me, the distance helps reveal which experience has continued to matter. A note written at once and an account written later answer different questions. I would not turn either the immediate mark or the lasting memory into a guarantee that the journey has been recorded whole.
