Query: It Really Helps -- It Do!

If I could find Dudson and Goodley I'd give them a great big kiss! They helped me. They saved my life and I want to say thank you. Thank you. I got that call reclutnce. The doctor told me it was the jittery kind, I think. So, the thing I did was something what Dudson and Goodley write about in this book -- I put an elastic band around my head (cause that's where I think the call reluctnc is) and when I don't make sales call, I let that rascal fly. It hurts for a minute or two, but I don't care. No jits. So, buy this book. I know you will like it. And if you don't want to wear elastic bands to work, don't worry. Dudson and Goodley got other helps for other folks. I tried sniffing the cologne like they said, but the doctor said it wouldn't help for what as I have got.
