Cleaning the house and in the kitchen I get obsessed with crumbs and dust near the cooker and sweep it up for the umpteenth time. I realise there is no end to tidying.
Like investigations of social life. The political scientist in me looks at street layouts, the sociologist orders the whole house, the anthropologist gets to grips with a room (even under the bed), while the psychologist picks at crumbs and the psychotherapist dusts (manically).
The mote in the eye no less.
