So basically you give your opinion on something and the next person gives a reason why you should change your mind and then their opinion on something.
Ex:
Person 1: Sweet potatoes are disgusting, change my mind.
Person 2: You can make delicious fries out of them, better than regular fries
College is not worth it, change my mind.
Get it?
Okay so....
Zelda is the best game ever, change my mind.
