You find some old museums very boring. And this is an example. The visit is required and you'll miss a lot. You dragged your feet around. You sleepily looked at the displays. Then you had an idea. In your mind, the old museum is filled with puzzles. The lights blinked. And your thoughts came true. Suddenly the old museum is empty and closed. You became excited. Finally you have something to do. You looked around the museum with light step and curious gazes.
