[Q]: This would have been a very short book if all of the racism and sexuality were to be removed. I read it for an Appalachian Literature class, and I felt this book was so racey that I couldn't enjoy reading it. The vulgarity in it is also not necessary, and I feel that it should not be called literature because of this.
[A]: Negative


[Q]: I was looking for a shower door that could open from either the left or the right and I did not want one to choose for me. This door ticks and fits all the right boxes in that department. I like the crystal glass effect too. It is very clear and allows a lot of light into the shower hub. It is frameless too which is what was asked for by the wife.Its sturdy quarter of an inch thick glass also is a nice feature. But most of all the pivot door is a feature I got on with too.
[A]: Positive


[Q]: I received this book from my ex-wife just after our divorce. At first I thought it was a crule joke. But after reading the life 101 book I realized that she could have given me A great gift.. Like the book states, Not all parts will pertain to you at this time, but it is a wonderful refference for later... I have purchased at least 15 of these books. and given them all away.. I usually buy one for myself and start rereading it when someone will say something that relates to a chapter in the book and I point it out to them and the next thing you know there goes another book... at this price it is easy to give them away...
