Not a metaphor

The day is bright but dark clouds brew above us. Its not a metaphor, these are the actual environmental conditions at the moment. I'm sitting and watching the people of Footscray walk about to and from the market, the occasional pairing of friends finding each other out and about on the street. They don't notice the clouds forming above. Not that they need to, but I wonder if later when it begins to rain, how many of them will be caught out and find themselves without an umbrella.
