Not my train

This is the notice for the train departing before my North Berwick one. I really do want to one day try this journey though to see what scenery is en-route.
Why was I off to North Berwick. Well it was to meet Donald and collect my car back off of him as he now has his new one from the garage.
He was to meet me at the station so I texted to tell him what time train I was getting and what time it would arrive. 
His reply was 'That's fine. Are you coming to Inverness?' 
I can sometimes feel a little cross with D but I sat on the train and tried hard not to appear cross-looking to my fellow travellers. 
I said in my head, 'I've told you I don't know how many times,  I'm not going up to Inverness this week'. And what's with the 'That's fine' business?
Then realisation struck me with a sharp blow. I'd texted the wrong Donald. How embarrassing could that have been!!! So apologies texted to Inverness Donald and train times texted to innocent-of-crime Donald.
