A scrawl on the dirty brick fence of a ratty block of flats on the edge of Newtown: there is nothing aloha about this bit of graffiti. And yet, and yet … It brought a ray of light into my day, enough for me to stop and, ahem, smell the hibiscus and take out my camera. The very word summons up imagery of clean turquoise waters, swaying palm trees and mai tais in tiki tumblers; a carefree life in the warm tropical sun. So perhaps it is a well-placed aloha after all.
