On the right day, a green plastic bucket can look like the underside of a curved palm leaf, every vein shining through clear in the sunlight. Perhaps maids clustered at tubewells hold up their buckets to the clear blue sky and the golden sunshine and think of the green roofs of their lost villages huddled forever under the dripping thunderclouds. Perhaps, in the right light, there is happiness to be found in the moulded curve of a green plastic bucket of the kind you can't find in any other city in India. Happiness in the sweet non-recyclable smell of wetgreen plastic. Plastic is sweet when clean and new, with the kind of no smell of a wet green leaf. It's strange how plastic green leaves can look when the sun catches them at the right angle. Anything with a shine can be faked at a distance from green leaves to plastic leaves to starched silken leaves. It's odd how unnatural nature can be when you try to pin her down to it. I think that somewhere in the heart of Bengal lurks a manufacturer who will make buckets like green leaves, stiffly curved and effortlessly elegant as a leaf is. There's an aesthetic insanity about it that Tagore would have understood, standing in his rust brown robes in the dark green shadows of Shantiniketan. You won't find a plastic green bucket like this anywhere else in the country.

Delhi buckets are heavy and fundamental, basically unimaginative. So are Bombay buckets, though with a little more luxe about them - you might find a Bombay bucket branded with a fake Cartier logo, impressive in its moulding, almost real, if there was such a thing as a Cartier bucket. But a green plastic bucket in Bengal is a different invention altogether. Everyone knows what colour you mean when you talk about a green plastic bucket in Calcutta. They nod their heads wisely and roll it down immediately from the furthest levels of their shelves. A child can roll a green plastic bucket like a ball and watch it bump and rattle down the stairs, laughing, thinking what a fun game and walk away without worrying about the colour. I sit on a white verandah and the green leaves around me wave and shine and turn to plastic.
