American tourists baffled by Brexit, its effect on the border, and Boris

They wanted to understand one thing and were nervous about two things, my American visitors.
I was driving from Leeson St into Stephen’s Green, when the wife of the couple screamed and threw her hands over her face. She was not expecting a bus to come around that corner, and when it did, thought it was going to go across directly in front of us and that we were going to T-bone it. Once her shudders reduced to occasional shivers, I asked which of them was planning to be the main driver and was relieved to hear the plan was that he’d be behind the wheel and she’d be navigating.
