[The kid starts to shake his head but stops. Maybe this is a change for their story? In that case Mount Gogyo would equal Mount Kaka, right? Even though that's not how they met, Goku understands they can't go around saying how they really met if they are hiding.]

Oh, yes! Mount Gogyo! I remember, I was born there and lived there until we met and you took care of me because I had no family! ... Is that right?

[If it wasn't for that last question one could have thought the kid was honestly remembering that. But no, he's just trying to make sense of things without thinking about things he doesn't want to think about.]
