There was a meeting of elementary school classmates, but I couldn't answer when I saw the picture on Kakao Talk. How should I deal with it? I haven't been in touch for too long, so please advise.

It can feel a little awkward to see a picture on your Kakao Talk and not answer it. But don't worry. Here are some of the steps you can take:

Expressing a positive response:

Look at the picture and express a positive response, such as, "Wow, you look so good getting together after a long time!"
To ask a simple question or to share news:

Ask about each other's news by asking simple questions such as "How is the meeting?" or "What are you all doing?"
Tell me your news:

If there is any news that you want to share about something that happened recently, it would be great. For example, mention a place you went to recently, a new hobby, or everyday news.
Recalling good memories:

Think back to those good memories, such as, "This photo reminds me of our past memories together. Wasn't that a lot of fun?"
Encourage more detailed conversation:

If you want to hear more details while reacting to the other person's conversation, you can try to induce more details, such as "I wonder what happened recently."
It is a good idea to express your interest in each other by sharing small stories with a brief impression. This will keep you in touch at any moment.
