Reconnecting with an Old Friend

A message came from someone I hadn't heard from in seven years. When I replied, he said he wanted to communicate via LINE. Since he's bilingual, I decided to send messages in English—it'll be good practice for my writing skills. With LINE, messages come a few times a day, so I'm using ChatGPT to help with my replies. Of course, I'm not just copying and pasting everything; I make some adjustments as well.
