[EX Q]: This is my mom's account. I had the pleasure of reading this book in English this year. I can honestly say, it is the single most boring book I've EVER read. You will NEVER find someone my age that enjoys this story. It has no action! No suspense! It isn't deep! Things don't symbolize anything. If they do, then you're thinking too hard. This book is not a classic. It is the worst. I'd recommend copying a dictionary before I'd ask you to read this pile. DO NOT EVEN THINK OF BUYING THIS.
[EX A]: Negative

[EX Q]: Good, sturdy platform for squatting under a barbell. Very firm. Laces are long enough to wrap around ankles, and back of shoe forms a fair notch to retain the laces and keep them from sliding up and off the shoes - would have been better had there been a rear loop. Shoes are better without the insoles because they put a spongy foam wedge under the heels. I replaced them with thin flat insoles from a pair of water shoes. One could cut the foam wedge and use the included insoles. There is no raised heel other than that foam wedge. They run true to size or slightly tight.
[EX A]: Positive

[EX Q]: Firstly, I find it startling that Vintage would deign to publish something so poorly written. The semi-literacy of this prose (I'm being generous) does, if nothing else, suggest that Miss Souljah didn't use a ghost writer. The words, in all their ghettofied glory, are hers. Booker T. Washington would have wept. While I can appreciate to some extent this woman's pathological disgust of whites, I cannot understand the roots of her homophobia or anti-Semitism. Her easy-way-out philosophy (Everybody's to Blame Except Me) is the very thing that keeps her where she is.
