[Q]: Dear potential sucker,My first airbed by intex sprung a leak in about a week, so I obtained a refund. I bought this model next, and it lasted almost twice as long!I am now on my third. I should have learned my lesson, but my current intex airbed has been around for about one year, and currently has 9, count 'em, NINE leaks. Everytime I patch one, another springs.Intex also makes inflateable boats. They must get sued for a lot of drownings. No wonder they have no email contact. If you buy ANY intex airbed, you are buying utter garbage.Sincerely,SidWa State

[Q]: I read Nathaniel Hawthorne's Scarlet Letter for my Advanced English 11 class. This is not a book I would normally have picked up and read, but I am glad that I read it.The Scarlet Letter deals with themes of love, society's oppression, secrets, a character finding herself, as well as numerous other classic literature themes. I found the book itself to be challenging to read, but I liked the story. Hawthorne explores when feelings and passion conflict with religion, which was fascinating to consider from a religious perspective.Although I did not enjoy the book much at the time I had to read it, it proved to be quite useful when I took the AP Literature and Composition Test this year. When I had to choose one book to frantically review the day before the test, this is the book I chose. Sure enough, this is the book I used for the AP test as a reference.This is an essential book for anyone taking AP Literature.
