Gentleman, lets get one thing straight:
The Wall, has nothing to do with her, it has to do with us... When WE turn 29, we enter our prime, mainly because this is the age, where we can socially acceptably date out of the best dating pools, 18-29 and 29-39... The Wall, is the idea, of her now having to compete with the rest of your new options.
She wants, simply, what she cannot compete to get... You see her desire to just have a simple attachment to the unobtainable, over a whole life with the obtainable?
Spinning Plates, to me, is about crafting an unobtainable mindset and we can see that power on display here.
