It probably did as you were thinking it, and even as you were writing it. But a funny thing can happen between the keyboard and the chair. It's as if an image of what you want to say gets burned into your brain, but somewhere along the way parts of that image fade and not all of your message makes it to the final destination.
The good news is that you can probably unpublish your post or remove the gobbledygook from your site or trash the printed copies and revise that paragraph. And, if you catch it early, there's a good chance not many people have seen it. On the other hand, if it's been up for a while or you've already mailed it, and if it's been shared among a wider audience, you may not have a chance at damage control.
You know where this is going, don't you?
