Gestures can be revealing. Ask English speakers about the difference between yesterday and tomorrow, and they might thrust a hand over the shoulder when referring to the past
and then forward when referring to the future. Such unreflective movements reveal a
fundamental way of thinking in which the past is at our backs, something that we "leave
behind," and the future is in front of us, something to look forward” to. Would a Yupno
speaker do the same?
