Go to the nearest jewelry store and buy everything in it. Wait an hour, return it as per the refund policy. If there is no refund policy then I would sell it off. Even if I lost 50% on the sell back, that’s still half a mil in cash.
Most popular jewelers have at least a 30 day refund policy.
A baby born on Dec 31st is 1 year old, and the next day would be 2 years old … A 2 day old baby would be considered 2 years old. Glad they decided that this was beyond odd.
