Oh, boy.....Martha has a new favorite word and it sounds like vine but it starts with an "m." Yep, MINE! She has a little brother who thinks the world of her...he's so little he can't quite pronounce her name so endearingly she's answering to Maffa! Maffa doesn't want to take turns or share her toys. Her parents decide to let her have it her way and she plays with her toys all by herself and doesn't share. But Martha is about to learn that life just isn't as good when you have to play all by yourself. So, she decides to give sharing a try....well, a little try.
