I came to your post by chance and immediately my memories, passed like a movie of a bittersweet experience that allowed me to understand the magnitude of how this event changed the world.
When you pose the question: would the world go back to the way it was before? from my point of view NO; fear changed humanity, the pandemic put death in front of our eyes and sat on the couch of many homes and hospitals to show us that uncertainty is what has set the tone in the past-present-future.
Greed and power took center stage.
