Then said they to him, "What shall we do to you, that the sea may be calm to us?" For the sea grew more and more tempestuous.
 So even we in ordinary life do not always address the same person in the same way. Suppose the case of a judge, and of a barrister who is the judge's son addressing him in court. Do you think the barrister would so far forget the court as to call the judge his father when addressing the jury, or even the judge? Or do you suppose when at home in the intimacy of his father's house that his son would call the judge "my lord," just as he and all else would in court?
