Hurry, Leo! You don't want to be late. Leo Lausemaus may be a little mouse, but he's just like all the other little children in the world. Getting up this morning is not at all easy for the little Lausemaus and he also dawdles at breakfast and on the way to kindergarten. His mum, the kindergarten teacher, his friends - they all have to wait for him. But then he realizes that it is not nice if he has to wait himself.
