Pikachu, we choose you! Er… no, we're totally not playing Pokemon. We're not that nerdy. (Actually, yes we are, and it's awesome.)
When you really think about it, everything that happens in this story is the result of the choices Midas makes.
So everything that happens to Midas is his own fault, right?
And why do we care? Because it's so different from most other Greek mythology. See, Greek characters are usually subject to fate. This means that they have no control over what will happen to them—their choices are made unimportant by their destiny.
But Midas breaks this rule. For better or for worse? What do you think?
