I hate mice! I know it may seem silly but I do. They are so small and they scurry around invading house holds, scratching walls at night and keeping me up paranoid, thinking that they will crawl across me. We don't even usually have mice problems but the few times we have, I have not been happy! I couldn't stand it when mice came into the dorms in winter. EEK! Mice are my number one fear. What are you afraid of?
