In his last years Bernard had a lot of time to take care of very important projects. Actually, he wanted to write a book about languages and their origin, which always fascinated him. He also spent a lot of time writing his new book "Between you and me" for the English lesson. This book specifically focusses on group work. Unfortunately, he could not finish it completely. This book is full of great ideas and many teaching materials. We decided to finish this book because Bernard has been working on it for years and this would be in his spirit. The book is unfortunately not complete, but we hope that it will be useful for you and your students.
