There, she mistakes the new teacher of her daughter with the renovating carpenter, which is quite alright with the teacher as this gives him plenty of opportunity to enjoy Conny’s company. Meanwhile, however, Bert as well has started to understand how good it is to have a cosy home. He comes to Munich in order to win Conny back.
