I spend a lot of time in the library as well. Rarely am I not tucked away in between shelves of books, either at home or in a shop or in the aforementioned library. Though, I hate the library because of all the people. I'm an introvert and a recluse and I have trouble seeing the point of the world being so stupidly crowded all the time. For these reasons I love to ride my bike at midnight when I can be alone.
I'm not a very careful person, but I am neat and a little ostentatious.
