It took a while, but eventually I managed to make a distinction between my colleague TF and student AA. This achieved, I climbed into TF’s car for our trip.
Our first destination was Bristol. Here TF showed me the house that he was in the process of building.
Then we arrived in Edinburgh. We toured the Old Town first, then stumbled into a new development of skyscrapers.
Suddenly TF admitted that he was lost. I forced him to stop at a filling station so that I could buy a map.
