I read about a guy named Robert. Fairly well known in certain circles. Famous, even.
One day he stepped onto a balcony in front of thousands of people with millions more watching on TV.
He was wearing a dress.
Robert said "my name is Leo." #LeoXIV.
The whole world said "Hi, Leo". This is exactly how hard it is to call someone by their preferred name.
