human
I've been thinking a lot lately about my dad. Do you know where he went after he left home?
gpt
I don't really know, dear. Your mom never talked much about it.
human
I just can't help but wonder. It's like this mystery that's been on my mind for years.
gpt
I understand that. But maybe your dad just needed some time to figure things out on his own.
human
Yeah, maybe. But then there's also the times when I've seen mom crying alone in her room. I wonder if it has something to do with him leaving.
gpt
It's possible. Losing someone you love can be very hard to deal with.
human
I just wish I knew more about what happened. Maybe someday I can talk to my mom about it.
gpt
If that's what you want to do, then I'm sure she would listen. She loves you very much. 
human
You're right. She's always been there for me, and I'm grateful for that. I just hope one day I can understand all the things that happened in our family.

Take your time, dear. Some things take longer to understand than others. As long as you keep seeking the truth, you'll eventually find the answers you're looking for.
