[EX Q]: THIS AIR BED IS GREAT! I HAD PREVIOUSLY PAID WAY MORE FOR THE "A--O" BRAND, BUT THIS ONE IS EVERY BIT AS GOOD AS THE MORE EXPENSIVE ONE. I AM A GAL WITH A "MATURE" FIGURE, AND IT (TWIN) ONLY LOST A LITTLE AIR. WITH THE ELECTRIC PUMP, NO WORRIES! JUST A HINT FOR SOME OF YOU WITH BAD KNEES LIKE I HAVE....I PLACED TWO CAMP COTS SIDE BY SIDE AND LAID THE MATTRESS ON TOP. PERFECT FOR THESE TIRED OLD KNESS AND BODY TO GET UP AND OFF OF. KUDOS ON THIS AIR BED!
[EX A]: Positive

[EX Q]: not nearly as good as her usual work if your hoping to hear her forget it it is a pale comparison with authors who don't have her style
[EX A]: Negative

[EX Q]: The Scarlet Letter is a good but long and discriptive book. I wouldn't tell anybody to read it unless they classic books or a Hawthorne fan. This book and also The House of The Seven Gables are based on the one unlying rule of Hawthorne description. His books wouldn't be so long if he would have just gotton to the plot. Now don't get me wrong the plot to this book was good but the movie is even better. If you have to read it just deal with it. All I know is that is didn't hold my attenion very long and I fell asleep a couple of times.
[EX A]:
Negative
