We should have envied her for having located someone without whom she so firmly felt she could not survive, beyond the gate let along in a bare student bedroom in a suburb of Rio. If she had been able to view her situation from a sufficient distance, she might have been able to recognise this as one of the high points in her life.
Curiosity might be pictured as being made up of chains of small questions extending outwards, sometimes over huge distances, from a central hub composed of a few blunt, large questions.
