Q: At 80" iong, this is an extra long twin, not a standard twin. Consequently I had to take back the sheets I bought, as they were 5" too short. I would have ordered a different model had I known that 80" wasn't standard. It's easier just to replace the sheets and I don't have time to send the bed back.

A: Negative

Q: This book is one of many written during the "Bubble Era" by "gaijin" (primarily Americans) who really knew next to nothing about Japan, yet somehow found a publisher, usually Japanese. Another of this quickie genre published about the same time was a book for teaching profanity to Japanese studying English."Learning to Bow" may by an accurate account of the author's experience living in Japan and teaching in the JET program. However, that's all it is. It's full of cliches, sweeping generalizations, and offers no insight into living in Japan or understanding the culture. What could the writer possibly know after only two years?

A:
Negative
