[Q]: I purchased the Intex airbed to replace an Aerobed that our cats "loved" too much during a guest visit. Comfort wise, the Intex wins hands down-supportive yet comfortable as well. Convenience wise, it inflates a little slower than our old Aerobed (albeit, there is more to inflate) yet it takes up less room when rolled and stored in the sack that comes with it. The only reason I didn't give it 5 stars is because it is VERY high, so a restless sleeper can fall off pretty easily.
[A]: Positive


[Q]: I had seen this authors' works offered for free on the Kindle page and since the price was right downloaded two of them. I was happily reading "The Lamp In The Desert" when I got to location 2458-61, and there in the middle of the page was the "N" word. Now I realize these books were written in a different time, and people had different morals and people were unenlightened, my problem now is, do I want to read a book written by someone so obviously contemptuous of me, no matter what decade the writer lived and worked in? I think the answer is NO! I was truly enjoying the book up until location 2458-61, and had even gone so far as to call my sister and recommend them to her. I am truly trying to be a bigger person and but I cannot truly support people who do not respect me. I am deleting this book and the "Rosa Mundi and Other Stories" today. Life is hard enough and I shouldn't have to fell insulted by something I bring into my home for pleasure. Sorry Ethel, ya gotta go!

[Q]: Plain Style was written in 1985 by Christopher Lasch, a history professor who was frustrated with his students' lack of writing ability. There are six sections:Elementary Principles of Literary ConstructionConventions Governing Punctuation, Capitalization, Typography, and FootnotesCharacteristics of Bad WritingWords Often MisusedWords Often MispronouncedProofreaders' MarksApparently Lasch's frustration with students went beyond just their writing skills. "I keep simplifying my course in 20th century American history, but the students keep getting dumber faster than I can simplify it," Lasch wrote in a letter to his father. "Every year the illiteracy gets worse."The current book was published after the author's death and includes an introduction by Stewart Weaver. The introduction is disproportionately long, taking up 42 of 121 pages.
