Carla hesitates. She is 37, she is married, possibly pregnant and she is supposed to be happy while she travels towards summer vacation along with her husband and a jet ski hooked to the back of the car. But maybe she doesn’t want to be there. Maybe she prefers to be hitchhiking with a random Norwegian backpacker heading to a beautiful national park where she could walk among big trees and talk about birds and old pop songs with the park ranger. Yes, maybe that would be better.
