I have been shy most of my life. My DH has stated that he never knew I was so shy. But if you're going to get anywhere or learn anything, you have got to introduce yourself and ask questions. When you go to the retreats ask if there are any others who are going from your area. Let everyone on the QB know what retreat you've signed up for and ask if any of them are going also. You may be surprised to see who's going. Then see if you can arrange a meeting place. Just have fun.
