Why did the bank give Tyhee a lot of extra time?  What were their options? 

They could have pushed Tyhee into bankrupcy and they would have gotten back far less than the full amount they were owed. 

Or...they could have given Tyhee more time confident that Tyhee had the gold and that was their best chance to recover all of their money.  We are glad they chose this path.  They are a business, not a philanthropist.

Now...my question remains.  What does Tyhee have to sell for in order for the bank to ecover all of its money?
