What is the meaning of "There is nothing so bad that it couldn't be worse" ?
Does it mean "The situation is not so bad. therefore, the situation couldn't be worse" or "The situation is so bad. therefore, the situation could be worse"?
For example,
A: I have no money.
B: The situation where you do not have money is not a bad situation. Therefore, it will not get worse. You have no debts!
Does "The situation where you do not have money is not a bad situation. Therefore, it will not get worse. You have no debts!" mean "There is nothing so bad that it couldn't be worse" ?
