ABSTRACT
Consider the following two interactions between adults and children. In the first an exasperated mother is waiting for a train with three heavy bags of shopping and a young child who seems to have far more energy then she has. She tries to persuade the child to sit and wait for the train on one of the platform seats but the child keeps jumping up and running around the platform. Eventually, after telling the child to sit still on three separate occasions, the mother picks the child up, plonks him on the chair and, with her face about three inches from his she says: ‘You just move from there; you just move from there once more.’
