The strangest part of being invisible is that you are able to see things that are brewing in the invisible unformed space. They’re not non-existent, they’re just not fully formed, like a pregnancy, the child is there but hasn’t manifested into the world yet.
In the invisible space, you can see it is a boy or girl, it has blue eyes and red hair. You can see it will be bitten by the neighbor’s dog, get sick and die.
So here’s the worst part:
No matter what you say to the parents of the baby,
“Please move away for the sake of the baby!”.
“Please do things to protect the baby from that dog!”.
No-one listens! They might see and hear you, but they believe you’re a little crazy.
When “the thing” happens, you cry even more than they do, you feel the pain, then you feel their pain and then the pile it all on me pain of being unable to change things.
That’s the worst part of invisibility.
