I think it will depend on the situation and mood at that time. But if it a normal situation and feeling, I think I'll read a book. Because I like quiet places, so I go to the library often and I like books as much as reading is one of my hobbies. But you can always choose something else. For example, if a movie I want to watch is released or a movie filmed by a favorite actor is released, I think I will go to see a movie. In addition, I think I will go to the movies even if I am with my friends or in a good mood. However, if I am alone or depressed, I think I will go to the library or bookstore and listen to music and read a books. P.S. I'm worried about my house. I think the company was giving me employee accommodation, but they said there was no empty accommodation available.
