[Q]: Hawthornes The Scarlet letter is an okay book. It has an okay plot and okay characters, but the book is not one for teens of the 90's. I had to read this book for my English teacher and to tell the truth if it were not graded I would not have read it. The teens of today do not want to read about the ancient customs of puritan society. If it had been about the scandalous affairs of Hester and Rev. Dimmsdale it would still be a best seller. I think this book should be only read voluntarily. If you are thinking of reading it you may need to reconsider.
[A]: Negative

[Q]: I bought this first alert CO alarm for my home in Wisconsin.When I started to read the instructions I found that this product is not UL list! How can a safety item like this not be UL listed.I did some research and found out first alert changed testing labs to save a few bucks and do not use the most well known UL. What's up with that...So I returned this CO and purchased the Kidde KN-COB-DP-H Plug-In Carbon Monoxide Alarm. The Kidde unit cost less too, so I saved a few dollars! Always pays to READ THE FINE PRINT.
[A]: Negative

[Q]: I am well into the book and am enjoying it as I am a fan of Belva Plain. However, no where so far do I find the last name of Hyacinth's family or Gerald's family. They are Dr & Mrs Gerald Who? Am I missing something or was this intentional on the part of the author?
[A]:
Positive
