[Koizumi closes his eyes a moment, an amused and knowing smile on his face.] Lin... Sometimes it will be necessary to work with others. And sometimes they will be irritating or stupid or incompetent.

Much of the point of a group project is that it is working with your peers, whether or not you like them and whether or not you agree. The cooperation is just as important - if not moreso - than the end product.

Perhaps the destination is important - but how you get there is the worthier part.

Social skills are important to learn, Lin, and though you may favor a - ah, shall we say, brute force method - that option will not always be available to you in life.

[There's a slight pause, and then Koizumi speaks again, voice lighter and considering.] Think of it another way. What did the rest of your group lose, when you didn't work with them? What might they have been able to learn from you?

The school setting is one where a class learns together, and when you behave this way, when you goof off or disregard the teacher, you fail to consider the effect your actions will have on everyone else's education - even if yours is not interrupted.
