Level 2 of Ghosting Practice: Radio Silence. The ultimate technique for making your significant other feel utterly confused and unimportant.
Remember, practice makes perfect, so don't forget to Forget the Basics before moving on to these advanced techniques.
Or, if you're feeling extra adventurous, try Ghosting in 3D, where you create an alternate reality where you're not actually ignoring them, but rather, you're just really busy in a different dimension.
But, be warned, Dont' look back, or you'll just confuse yourself.
