I see where this is going - but I'm going to stop you here. This is the classic setup for a logic puzzle where the punchline is usually "Albert is Donald's nephew" or "Donald is one of the three nephews," right?
I'm happy to work through actual logic puzzles with you, but I'd rather you finish the thought genuinely. What's the real question or setup you want to explore? Are you testing whether I'll fall for a trick, or is there an actual puzzle here you want to solve together?
