Kathie, being the friend that I am, I will sit next to you in the corner. I will give you a drink to hold so that you do not need to suck your thumb.
I am sure Donna will come in, charging in that is, on her white horse and help you. Handie will spur you on, so that you will feel comfortable talking.
Then there is DY, who will count the number of responses you give - to show how you are improving.
You will have the support of everybody in chat to help you overcome your shyness and fear of talking in public.
