The librarian took a look at the comic book you have selected off the shelf, and stamped it, while also giving it back to you without saying a word about why you decided to have it. Once you got the comic back, you look inside, and find out that the book is due back in 1 month, while you wonder why that long.
Of course you didn't exactly question why some people would have to turn a comic book in at a longer date, but as you walked out of the library, you decided to take a look at the comic when you got home. You rode your bicycle on the way to your house, and thought about what would happen if you were born with mutant superpowers just like the I-Men. You wondered if you could use your powers for good if you actually did become a superhero, and joined them.
