Awwwweee! You are so smart! You are supposed to be in class right now learning about the history of your state, but instead you came here to learn why you were bored enough to type "asdfghjklkjhgfdsasdfghjkl".
You should be in class right now but you were bored enough to type "asdfghjklkjhgfdsasdfghjkl" on your keyboard.
