What would you say when you meet a classmate you haven't seen for years in the street?

When I met my junior high school classmates, it was also quite good at that time. "Come on, let's go to dinner first and talk at the dinner table." Let's talk about our recent living conditions and what we have done. Talk about the happy time together before, talk about what you have seen and heard, and talk about what you plan to do in the future. Talk about your own views, your own ideas, and the difficulties you are currently facing. There is no need to be so formal when chatting with good friends. There is no gap between two people. You can talk about anything. So when I meet my good friend, I can say whatever I want.
