In Life Is Friends, Martinet focuses on at-home entertaining - the dinner parties, cocktail parties, and informal get-togethers that are the key to creating lasting, fulfilling interpersonal bonds. So hear what Martinet has to say. And then, go ahead: Invite people over.
This book is more of an etiquette guide than a discussion about how to make and maintain friendships. Some of the stuff is obvious to me, but maybe helpful if you need to hear why you should be careful not to press the 'send to all' button when sending emails amongst groups of friends. There's a lot about how to deal with sending out invitations and practical things that I wasn't really looking for in a book about friendship.
