情景对话：
爸爸对小冬说：“我今天去郑州出差，不能亲自去接从乡下来的爷爷。你告诉妈妈，要她下午3点钟去松柏车站接爷爷。爷爷来后，你一定代我向爷爷问好，让爷爷别忘了到公园去练习太极拳。”
中午放学一回家，小冬见到妈妈，忙对妈妈说：“                                
                                                                           
                                                                           。”
下午放学回家，见到爷爷后，小冬说：“                                        
                                                                           
                                                                           。”
