The problem with bubbles is that you can almost never tell it’s a bubble when you’re inside of it. Somehow you think it will go on indefinitely. We like that narrative. It’s a lovely fairytale with the happy ending we all feel we deserve.
The analogy I like to use is that of fish inside a fish tank. They are oblivious to the fact that there is anything “outside.” When we’re inside a bubble most of use behave the way the fish do, oblivious the the threat of what’s outside. The concept of “outside of the bubble” makes no sense. All we experience is what’s inside. If there is an outside then, of course, it must be no different than what’s inside. The same rules should apply. That’s almost always a formula for a very rude awakening when the bubble bursts.
