Here was the lunch conversation between me and Dan, after I read the newspaper's front page story about Caster Semenya (the South African runner who has undergone gender testing):
Dan: She has a V but not a P. And they checked, but there are no Os.
Me: Or a U.
Dan: No. But there are Ts.
Dan: Very weird.
Me: Wouldn't that make her... ???
Dan: An H? Possibly.
Did I mention Katie was at the table, eating lunch too? That means we definitely can't use the real words. And now that she reads and spells so well, we can't risk it by even spelling the words.
Hence, speaking in code.
