"No..." he said, cautiously. "We each had enough toys."

I.. uh.. wh... h.... Huh. I don't think I could come up with a reply that they'd understand. There is almost a trickle of theft accusation in that reply. A sort of hint that their mind is entrenched in a different direction and that trying to move them would not be taken as good-hearted, but instead as a threat/scam. This reminds of a little tale from my family. My mother's aunt migrated from Greece to Australia, worked, saved and then helped several other family members across. Many decades later my parents organised a dinner and invited my mother's aunt over. They wanted it to be special so they freshly made pasta from scratch. If you've never had this before: the texture and flavour is a bit different to dry store bought stuff, I quite enjoy it. During the meal my parents hinted that they made the pasta themselves. My mother's aunt was shocked. "You can't even afford pasta? You should have told me you were doing it rough!".
