This book might be a little outdated, but I think it's because
it's outdated that it's fun to read! Etiquette is so lost in this day and age, and I loved learning from this book to apply what little class we should still be displaying when we are out with friends or meeting new people in different social situations.
Above all else - you still need to know what fork to start with at dinner, and how to set a table. That seems to have never gone out of style as far as I'm concerned, and this book properly teaches you in detail how to pull it off.
