Sixes and Sevens was the reply my Father would generally give to the greeting of "How's it going?". I adopted the phrase and assumed that it meant average, or slightly above. Instead Sixes and Sevens is an English phrase that means confusion and dissaray. The similar phrase "to set the world at six and seven", used by Chaucer, seems, from its context, to mean "to hazard the world" or "to risk one's life".
