Ran Zhihan actually didn't mean that at all. He just wanted his mother to know that even if his father lay there, they should stand outside and wait for a miracle to happen. As long as there is hope, a miracle might really descend upon them. If there had been no hope for these past years, how could he speak of being saved by a miracle?
"Mom, how can you say that about Zhihan?"
You clearly know he's just concerned about you all, which is why he would say such a thing. Since he's expressing his concern, why can't you try to understand him? Must you speak to him in that tone? Is it also wrong for him to be concerned about you? He's part of this family and has painstakingly taken care of our lives for so many years. Doesn't he deserve to show his concern?
