Welcome to your forth grilled cheese sandwich observation lesson. If you missed our first lesson, second lesson or third lesson, feel free to refer back to them before proceeding. And as usual, feel free to take notes.

As far as I know this is not a grilled cheese sandwich, and quite frankly it concerns me that you think it is. Please seek counseling.
