Gaia knows pity isn't the right reaction here. She's had at least a vague idea that Sephiroth's life had been very different from what anyone could refer to as a 'normal upbringing'. But Gaia is still a little surprised to learn that he doesn't seem to have even a frame of reference. From... observation of others' fortune if nothing else.

So there might be a flash of something like pity, quickly cleared away and replaced by the discomfort of trying to struggle for a description she's not wholly sure she knows a real answer for.

"To be honest, I only know what I've seen watching other families," Gaia admits in a way that sounds almost sheepish.

"When I lost my memories, it's not like I had to learn everything all over again." She'd forgotten people, much of her childhood, but it's not as if she'd had no recollection of what it was like to live an affluent life.

"But I suspect my parents were like most of Eulmore's citizens. Leaving my care to servants. And... there was never any indication they noticed when I disappeared. So I won't be offended if you think I might not know the answer to that."

Still, those words have the bearing of a conditional.

"But... I've seen a lot of families since I started living in the Crystarium. Mothers and fathers. I like to think parents that care for their children are interested in hearing about their day or just spending time with them..."

Gaia then huffs, looking embarrassed at herself.

"That sounds silly doesn't it? I'm sure there's more to it, but the only thing I can suggest is watching others with their children."
