一家三口散步归来,忽然看到单元门下正蹲坐着一个人,把三人吓了一跳,细看,却是老母亲。母亲这时也已睁开了眼,见儿子一家回来了,不好意思地笑了。妻说“:哎呀,来之前也不打个电话,我们好准备呀。”儿子一边提母亲的包,一边说妈妈的班车每天都要从火车站经过,提前打个电话,还可 A family of three walked back and suddenly saw a person sitting underneath the unit door and shocked the three people. It was the old mother. The mother also opened her eyes and saw her son’s family come back, laughing embarrassedly. The wife said, “Oh, we didn’t make a phone call before we came. We’re ready to go.” The son mentioned his mother’s bag while saying that the mother’s shuttle bus passes through the train station every day and calls in advance.
