Opinion seems to me to be a difficult word to start a sentence.
Some of the last words that get posted here immediately make me think of a sentence, sometimes funny (or at least trying to be funny) or serious. With some my fingers are dancing on the keyboard so quickly that there's all kinds of typos too.
When I don't feel an instant sentence in my head with whatever the last word is, I usually close the thread and go on to another thread, but today, guess what? You get all of these words.....*laughs hard.
