It was sent from Nairn on August 10, 1909 at 9am - so it was sent to and from the same town.
This is confusing, but better explained when you read the text - and remember that most people did not have telephones back then (a stamp cost half a penny at the time): "I shall send 3 pints currants on Tuesday with Baker. Please call there for them. These are all I have to share now all well."
Things like this make me think of how little we would communicate if we had to consciously put a stamp on every e-mail or Facebook post - and how much we actually communicate in this day and age - electronically, not personally. (As an aside, I HATE black currants!)
