"At that time, did you realize that something unusual must have happened?"
"At that time, I was still young and didn't really understand what it meant to have an accident. I just thought that my dad was busy with his work and maybe didn't want to answer my calls. It wasn't until the afternoon when I saw my mom sitting in the room, crying non-stop, that I realized something must have happened."
"So, you mean to say, your mother was the first to know about this?"
"No, it was my grandfather who first found out. After he knew, he told my mom. Because I was young, they didn't tell me directly, just mentioned that there might have been an accident. Since then, I've never seen my dad again."
"How could they be sure that your dad had an accident? Where did this news come from?"
