Rain and vacation

What are you supposed to do when the rain is pouring down outside and you have vacation? I guess I might find it cosy if I would be at home, but now when I am visiting my relatives I am caught in a house as a guest. As a guest you cannot organize your closet, clean your bathroom or do other useful things that you would do at home.
My small summetown is more like a watertown right now and I feel quite bored....Tomorrow or the day after I will go to Helsinki, don´t know if that is going to help my boredom....I am going to go and read a book.
