When 19-year-old Elizabeth Anne Bogert decided to start identifying as a man, his parents reacted in an innovative, witty and touching way.

The proud parents took out a second box in the Brisbane Courier Mail, "retracting" their previous birth announcement after their son informed them they previously got the sex wrong.

The note reads:

"A retraction – Bogert –

In 1995 we announced the arrival of our sprogget, Elizabeth Anne, as a daughter. He informs us that we were mistaken. Oops! Our bad. We would now like to present, our wonderful son – Kai Bogert.

Loving you is the easiest thing in the world. Tidy your room."
