If you pick up a glass vase and slam it on the ground its broken. You can say sorry to the vase but it’s still broken. To fix it you have to pick up every single broken piece of glass (probably cutting yourself in the process) find a glue thats strong enough to hold the glass together but gentle enough to not ruin it, spend the time fitting the puzzle pieces back together and even still nothing you do will ever renew the vase to its orginal form. It might look the same, feel the same, serve the same purpose but it will never be the same.
My mom gave me that metaphor when I was younger and now I know why.
