If you are looking for humility, you wouldn’t go hunting in Parliament.
There are displays of humility. Seldom does an MP win a candidacy or an election or promotion without intoning how humbling it is to have won. Democracy requires ritual magnanimity in victory.
But magnanimity stretches only so far. Winston Peters as Deputy Prime Minister in 1997 used to crow across the Chamber at Labour and the Alliance: “We’re here and you’re there” (in opposition). The present Deputy Prime Minister, Michael Cullen, did it more cuttingly: “We won. You lost. Eat that.”
