Yes. I originally proposed to meet them in Oban, assuming that they’d be going there to provision. Mum said no, on the grounds that it’s north of Craobh and so would be an unnecessary detour. Instead they want to pick me up at Dumbarton and go to Morrisons or Asda there; I want to go on to Balloch and meet them after they’ve been shopping - the station there is very close to the main road, looks like a nicer place to wait (if the weather is good), and means I don’t have to traipse round the supermarketBig ASDA and a Morrisons in Dumbarton, on opposite sides of the road, between two of the Dumbarton railway stations - Central & East. The other option is train to Oban and meet parents there - smaller supermarket, though...
We can figure these details out nearer the time, but thanks all for the advice to check on the Rest and Be Thankful pass beforehand.
