March Hare: Then you should say what you mean.
Alice: I do, at least – at least I mean what I say – that's the same thing, you know.
Mad Hatter: Not the same thing a bit! You might just as well say that ‘I see what I eat’ is the same thing as ‘I eat what I see’!
Alice's Adventures in Wonderland. By Lewis Carroll
What the March Hare says is good advice; you should say what you mean. Whether you're telling someone what you do or don't want, what you think or how you feel, or you're explaining how to do something, making a complaint, or making small talk at a party, there's one rule: say what you mean. Do it in a way that makes it easy for other people to listen and to understand what you mean.
