You should not freeload from other people.
Troy has been living at Donald's house for a few months after he lost his job and now Donald is asking if Troy is going to look for work.
Troy wants to answer Donald's question.
Troy tells Donald that he's going to look for work right away since he wants to free Donald of the burden of housing him.
Troy tells Donald that he'd much rather just continue to live there for free for a while, and he'll look for work sometime down the road.
Donald is delighted that his friend is planning to move on with his life, and he won't be there too much longer.
Donald is furious that Troy is taking advantage of his good will and contemplates whether to throw Troy out.
