Perhaps the easiest people to fall in love with are those about whom we know nothing. Romances are never as pure as those we imagine during long train journeys, as we secretly contemplate a beautiful person who is gazing out of the window – a perfect love story interrupted only when the beloved looks back into the carriage and starts up a dull conversation about the excessive price of the on-board sandwiches with a neighbour or blows her nose aggressively into a handkerchief.
We might have been ready to offer sympathy, but in actuality there were stronger reasons to want to congratulate her for having found such a powerful motive to feel sad. 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.

Socrates, on being insulted in the marketplace, asked by a passerby, "Don't you worry about being called names?" retorted, "Why? Do you think I should resent it if an ass had kicked me?
[T]he unsympathetic assessments we make of others are usually the result of nothing more sinister than our habit of looking at them in the wrong way, through lenses clouded by distraction, exhaustion and fear, which blind us to the fact that they are really, despite a thousand differences, just altered versions of ourselves: fellow fragile, uncertain, flawed beings likewise craving love and in urgent need of forgiveness.
It seems that most of us could benefit from a brush with a near-fatal disaster to help us recognise the important things that we are too defeated or embittered to recognise from day to day.
If our lives are dominated by a search for happiness, then perhaps few activities reveal as much about the dynamics of this quest - in all its ardour and paradoxes - than our travels.
