The husband helped himself to Person Y's apple while feeling hungry and enjoyed it. Person Y doesn't mind taking an apple or two from their garden, but it's still their property. The wife suggests asking apple orchard owners before picking apples next time, reminding them of past apple picking adventures.

You know the other day, I was in Person Y's garden and I saw a ripe apple on the tree. I couldn't resist and ended up eating it. 
gpt
*laughs* You just helped yourself to their apple?
human
Well, I was feeling hungry and it looked so juicy and sweet. Plus, Person Y doesn't mind if anyone takes an apple or two from their garden.
gpt
I'm sure they wouldn't mind, but it's still their property. You should have asked them first.
human
Yeah, you're right. Next time, I'll make sure to ask before taking anything.
gpt
That reminds me of when we went apple picking a few years ago. Remember how we filled up that whole basket and made apple pies?
human
Oh yeah, that was so much fun. We should do that again soon.
gpt
Definitely, but maybe this time we should make sure to ask the apple orchard owners before picking any apples.
human
*laughs* Good point. I don't want to end up like the apple thief in Person Y's garden.
gpt
*laughs* No, we definitely don't want that. But I'm glad you enjoyed that juicy apple.
