Lucy: Why do I have to go fishing with you when I'm busy writing my novel?
Natsu: Well you were getting in a funk 'cause you couldn't think of any good ideas, right?
Happy: Aye. When that happens you should go out for a change of pace.
Lucy: But why fishing?
Happy: Because fish are my bread and butter.
Lucy: And your point? Why should I have to fish up your favorite food?
