That's not how it happened

Take Oliver's part first, then Grace's. They argue like old friends: quick, sure of themselves, never really angry. Copy the surprised drop in "Oh. That's my hand on the wheel." and the warm, slower last two lines.

1. OliverDo you remember that trip to the Highlands? Our first year in Edinburgh?
2. GraceHow could I forget? We spent six hours lost in the rain.
3. OliverBecause you took the wrong exit at the roundabout.
4. GraceMe? That's not how I remember it. You were driving.
5. OliverNo, you drove. I had the map. I was the only one who could read it.
6. GraceOliver, you held the map upside down for an hour.
7. OliverThat never happened. I think you're mixing me up with someone else.
8. GraceThen why do I have a photo of it? Hold on.
9. OliverYou kept photos from twenty years ago on your phone?
10. GraceI keep everything. Here. You, the map, the sheep. Look closely.
11. OliverOkay, the map does look upside down. But who's behind the wheel?
12. GraceOh. That's my hand on the wheel.
13. OliverSo you were driving. Let me set the record straight, for everyone.
14. GraceFine. I drove, and you navigated us into a field.
15. OliverIt's all coming back to me now. The farmer with the tractor.
16. GraceHe pulled us out and gave us tea. Best part of the whole trip.
17. OliverShall we call it a draw, then?
18. GraceA draw. But I'm keeping this photo forever.
