[EX Q]: Wow..thats basically all i can say. I bought the cd, then realized that they were playin live like 20 minutes from my house. They put on an amazing show! They closed it with do you call my name, then went backstage. The crowd started chanting, "ONE MORE SONG!!" The drummer came out and started playing again. Then all the rest came back out and played one last song. Ra is underrated and a great bunch of guys. I got my cd autographed by all 4 and i got a picture with them. Buy From One, Duality, and SEE THEM LIVE!! My ears are still ringing.
[EX A]: Positive

[EX Q]: I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.
[EX A]: Negative

[EX Q]: I was really disappointed in this book and surprised that so many people think it is a wonderful story. It was such a depressing story and reflects all of the worst things about the way women were treated in that time. I don't think this story had any redeeming qualities and very few likeable characters (even Tess was quite irritating at times with her pride getting in the way of asking for help to make her life a little easier).
[EX A]:
Negative
