Una vaca muuuy triste

There is no cow sadder than Muriel. She only sees the terrible side of things; not even her own birthday party makes her happy. When the little lamb, tired of trying to cheer her up, catches her pessimism, Muriel realizes that she can only help her friend if she starts to smile. A great story that encourages reflection about the management of feelings and emotions. No hay vaca más triste que Muriel. Sólo ve el lado terrible de las cosas; ni siquiera su propia fiesta de cumpleaños la alegra....
