Mark Thackeray: What we saw yesterday is that to a considerable extent, we control how we are perceived. "Yo!" Gets you one response, "Excuse me, sir," another. When we address someone with respect, we are more often than likely to GET respect - not always, but more often than you think, and if you're smart, that ought to be enough. Common courtesy - "please", "thank you", "excuse me"... magical words, magical words.
