The park where I take my walk in Bangalore is not as immaculate as many in the city are. It makes do with a daily sweep of the walkways by a somewhat lackadaisical fellow who must be in the employ of the municipality. He has a family, I realised, when occasionally he would not turn up in the morning and instead the sweeping would be done by someone who seemed to be his wife. She, of course, would do a better job.
