I don't know what to do. My friend is marrying someone who isn't Catholic. 
gpt
That's their decision to make.
human
But doesn't it go against our beliefs?
gpt
We can't control what others do. All we can do is respect their decisions.
human
I just feel like I should say something to him.
gpt
You could share your concerns with him, but ultimately it's his choice.
human
Yeah, you're right. I just hope he knows what he's getting into.
gpt
Well, we should focus on being supportive friends during this exciting time for him.
human
You're right. On another note, thanks again for paying for those books I ordered.
gpt
No problem, honey. Did you find the books helpful for your homework?
human
Definitely. I ended up getting an A on that math assignment.
gpt
That's great to hear. I'm proud of you.
human
Thanks, dear. Speaking of school, I should probably start studying for my upcoming history exam.
gpt
Good idea. I'll make us some tea to keep us focused.
