Misjudging someone’s use of silence can take place in many contexts and on many levels. Take pausing for example. One’s conversational style may be marked by frequent pausing, thus giving room(or time)for the discourse partner to jump into the conversation by taking his or her next turn. Some speakers, however, may think that the pauses others leave for them are not long enough to claim the floor(发言权)without being rude, while it may be the feeling of the other party that longer pauses would create awkward silences. Such differences in the perception and valuation of pauses may lead to conflict. The person who does not tolerate long pauses may wonder why the other does not want to talk, whereas the person who needs longer pauses to take a turn may think of his or her partner as intolerably talkative.
