有分寸

• The introduction was followed up on his side by a happy readiness of conversation - a readiness at the same time perfectly correct and unassuming ; and the whole party were still standing and talking together very agreeably , when the sound of horses drew their notice , and darcy and bingley were seen riding down the street
  一经介绍之后，他就高高兴兴，恳恳切切地谈起话来既恳切，又显得非常正派，而且又有分寸。他们正站在那儿谈得很投机的时候，忽然听到一阵得得的马蹄声，只见达西和彬格莱骑着马从街上过来。
