The first rule when teaching conversational English is always to structure a question in a way that prevents the student answering with a simple ‘yes’ or ‘no.’ This is exactly what an ad should do.

If the reader answers ‘yes,’ great, you’ve found a potential customer. And if they said ‘no’ then that means they’re not interested, right?

But what if the ad was rewritten to make the reader question his or her lack of interest?
