The unpleasant nativeLogic Level 1
You are on an island where the natives either always tell the truth or always lie.
You encounter a scowling native in the jungle one day.
"Are you a truth-teller or a liar?" you inquire.
"I refuse to tell you!" he snarls, and stalks away. You never encounter this native again.
Was the native a truth-teller or a liar?
