Just when the author seemed to have put his foot in it, the subsequent sentences doesn’t confirm that, but the context brings out more definition and clarity. And it sounds just right.
Some people I have met love to prove how clever they are by focusing on the small things or parts of things and making something of it rather than converse based on context. It may make for ‘thrilling’ conversation sometimes (and stimulus for characterization and dialogue, either as drama or comedy), but do this in some forums and contexts and you’d put your foot in it. The context, as I’ve alluded to above, is never adhered to. Makes for mild or stimulating comedy and other forms.
Though a little discretion is advised at times because some people don’t like smart one-liners without a basis in context–which proves that a writer needs to know their setting before embarking on their character’s “witty, clever” chat, for what is deemed wit somewhere, is deemed nit witty elsewhere.
However, a genuine surprise value in settings is always a delight. For example, in the movie Jerry Maguire, the title character “flips out” and joins the “mere mortals”, because he has a crisis about what he’s been doing, but he’s a top football agent who should be at his game and not making moral decisions–isn’t that the way of the sport’s world? But Jerry Maguire adds surprise value to the setting.
