A very good classmate came back from the army and now added WeChat. What should I say?

Take the initiative to chat. You'd better talk about him. The first thing is to say hello, and then look back on your original feelings and compare what happened at school. Or the feeling of meeting for the first time. This will help to bring your relationship closer.

The most important thing is to talk about your feelings or gains as a soldier. Funny things about being a soldier. Do you have a girlfriend? Have you ever been flustered after being a soldier for so long? The main purpose is to bring feelings and relationships closer.

Hope to adopt, you can have a private chat if necessary.
