eloquence

I wish that I could sound as eloquent when I speak as when I write. I would like to be able to stop a conversation, go back and edit for clarity, maybe look up a word in a thesaurus. I know that if I could edit myself, I wouldn't say "stuff" quite so often during a job interview. Wait, did I really say "stuff" as often as I think I did? If I could stop and review the contents of my words I would know. Sigh, someone needs to invent an electronic interview editor.
