Family suppers often involved a game: if one of us children made a usage error, Mom would pretend to have a coughing fit that would go on and on until the relevant child had identified the relevant error and corrected it. It was all very self-ironic and lighthearted; but still, looking back, it seems a bit excessive to pretend that your small child is actually denying you oxygen by speaking incorrectly. The really chilling thing, though, is that I now sometimes find myself playing this same “game” with my own students, complete with pretend pertussion.
