Nairobi PTSD?

After we crossed the border on the way back from Denmark, my dad left the Autobahn to look for a restaurant that he remembered from his youth. He wasn't quite sure anymore where it was, so at one point, he stopped by the roadside, and he and my mum looked at the map. This is on one of the regional roads, in the middle of fields (orderly roads, orderly fields). No traffic.

Then a car stopped opposite and a man got out and walked towards us.

I sat in the back and had the craziest surge of panic when I saw him approach.

He bent down to the car window and asked if we needed help. My dad told him where we wanted to go, and he gave us directions. My parents were delighted that he had been so thoughtful. I breathed out slowly and gently as my panic subsided.
