Some people say there are three kinds of people, to demonstrate this, let's have a look at the following scene, it is morning, and Kakashi is late again, so team 7 has some time to kill.
Somehow, Sasuke gets bored. Very bored, so bored actually, that he decides to just do something about it. Sasuke is the first kind of person, the person who makes things happen.
After seeing what Sasuke did, Sakura could only look in surprise. She is the second kind, the person who watches things happen.
Naruto was the third, he who wonders what the hell happened.
