“As for my own answers to any of this? I have none. I'm far more confused than before I first went. I've had no great epiphanies, no profound realisations, but since returning home I've resigned myself to this one thing: that, putting the economics and politics of it all aside - naive as that may be - what it all boils down to is individuals. It's a simple interaction between just two people: one, a person with opportunities and choices, and who could get a flight out tomorrow should they choose; the other, a person with few options - if any. If nothing else, it's a gesture. An attempt. Food and a tent for Toto. Burns dressing for Jose. A little operating theatre with car batteries and boiled instruments, where Roberto can ply his trade. Free HIV treatment for Elizabeth, who'll never be cured and will always live in a hut anyway, but who'll have a longer, healthier life because of it. And sometimes it's little more than a bed in which to die peacefully, attended to by family and health workers... but hey, that's no small thing in some parts. My head says it's futile. My heart knows differently.”
