Have you ever noticed how some people, who seem very witty and intelligent in their writing, can surprise you with their limited vocabulary when they speak to you in person? Not everyone who is so talented at word usage is so handicapped of course - Stephen Fry is the perfect example of a human dictionary and thesaurus (of course, he's not just wordy, he's very properly clever too).
Well, I am definitely one of those people who will disappoint in real life. In my writing I can turn a nice phrase now and again, but I have usually pinched it from somewhere - my name of Lady Wordsmith is rather fallacious really, and I gave myself the title as more of a target than a prize earned on merit (look out for future hub, 'Pretending to be Clever - how I do it'). In real life I am actually much less verbose. Well, no, actually, that's not true - I am very talkative, but most of what I say will bore you to tears and you will wish you hadn't asked. I am very well used to feeling chagrined when my powers of recall let me down in a conversation, and I am left stumbling over my words. I am sure many writers experience this same agony. I would imagine that it is similar to the way a stand-up comedian feels when a fan asks him or her to tell a joke, and he or she cannot immediately think of a good one, so he or she plumps for 'what's brown and sticky? A stick.'
