What are two examples and 1 quotation from the book explaining how Tom is a bully ?

Tom is never happy. He seeks conflict. He is a physically powerful man always looking for a fight. At one point Nick observes, "I felt that Tom would drift on forever seeking, a little wistfully, for the dramatic turbulence of some irrecoverable football game."

In another point he even breaks Myrtle's nose with the "short, deft movement" of his open hand.
