Dude, this happened to me a few months ago. Met a big donor for the organization I am the director for, as he is a billionaire and is not in town much, and my incompetent talking mechanism of blocks, repeats and contortions embarrassed me to the point that I worried I could lose my job. He can’t possibly think I am competent! I looked up to him before, but his reaction could be easily interpreted as disgust, though I tried to stay positive. It TOTALLY sucks sometimes! Good news, I still have my job some five months later, so, yay. Still haunts me sometimes. Wish I worked in a cave. We could all work there and exclusively communicate with text messaging. Really though, more and more I am learning to take a little time to laugh at the absurdity of it all. I really do sound like an unfortunate, funny mistake. I know I still have a lot to offer, and I have huge respect for those I can still call friends and colleagues despite my talking issues.
