At the end of the trip, they were a little unhappy and went home separately. Carter's family cooked a sumptuous dinner to celebrate his safe return, and Cole had lunch alone in a big empty and cold house. At that time, there was a sharp contrast between them, which made people feel that with so much money, family was the best thing in the world. Carter was seriously ill that night, and their previous unhappiness was over. This is true friendship. Even if you are angry one second, you can forgive the next. Perhaps the friendship between Cole and Carter comes from being in the same boat, so they appreciate each other. It is what Zhang Ailing said: Because you know, you are merciful.
