The man on the radio talked fast, as always. Nuno let the words go past him. He watched the boy draw a face on the glass.

“It's eight o'clock,” said the man on the radio. “Time for the traffic news with Kevin. Kevin?”

“Kevin isn't here this morning,” said the man. “He's just sent me a message. He's stuck in traffic.”

Nuno heard every word. For a second, nothing happened. Then the joke arrived, all of it at once.
