In 1917, you are born, a fine baby. Really the only thing wrong with you is the third eye.
The midwife says Oh that’s just a baby eye, we used to see those all the time before they put iodide in the salt. What a hoot.
Your mother is reassured by this.
Your father takes a short performative breath and asks Will we be charged extra for the third eye. He says that No one asked if we wanted a third eye.
The midwife says No it’s cool, the baby eye is free. It’s like baby fat. It will just melt away, close up by the time the kiddo is 12 or 13. Sometimes before they’re 10. Everything they see through it will be forgotten. It will even disappear from any properly formatted digital photos. If you do choose to have an oil painting or sculpture made of the child, that won’t update automatically. You’ll have to bring it in and in all likelihood it’ll be out of warranty.
So it does cost extra, your father says with a thin vinegary smile.
