When waiting for someone at the mall, the most convenient and interesting place for me to wait up is the bookstore. It doesn't matter if it's the NBS, Powerbooks or any other bookshop for that matter. I love books and these bookstores are heaven for me.
Anyway, I was at NBS recently and I wound up buying books in the end. I bought 2 English books and 1 career reference book for my youngest brother and bought one for myself.
The Elements of Style, Fourth Edition by William Strunk, Jr. and E.B. White is a classic reference book for English requirements. I was told that this book's a gem for every English student and aspiring writers (in my case, I'm the frustrated one). You gotta love English to appreciate this book.
