I'm in St Bart's (the island, not the hospital). All the way here, I wondered why people went away in winter. You always have to leave so early that you feel like you've got deep-vein thrombosis before you've even reached the airport. You always have to go halfway across the world for sun, rather than, say, Italy. You always have to travel with French people, who all (and this isn't racism, it's a tested fact) fidget like toddlers on aeroplanes and often give the very real impression that they're about to open the safety door and attempt absent-mindedly to go for a stroll. Sleep deprivation somewhere near the point of arrival has always caused you to fall out of love with either your travelling companion or your new swimwear. And then you arrive, and it all becomes clear.
