Language is fascinating for revealing. Some people don’t ask in restaurants for “some” ketchup or “the” ketchup anymore. They ask “where” is “their” ketchup. This means they are not only taking for granted that the restaurant has ketchup but that they are entitled to it.
So ketchup seems a basic need these days. Even a right. At this moment, for example, there are people talking in front of me and thinking I am listening when I am actually writing about ketchup. And I don’t even like it!
