In The Outsiders, the Greasers' feelings about rough breaks are brought up in chapter three. The boys are fighting about how the boys feel at home. Ponyboy lashes out at telling Johnny that he is not wanted at home. After a while, Ponyboy apologizes, understanding that life is not fair for any of them.
Two-bit states how the reader can assume all the other Greasers feel: "Like it, or lump it." What this means is that a person must either like a situation or simply accept it for what it is (given a person cannot change it). Therefore, it can be said that the Greasers deal with life in this way. They choose to like the cards life deals them, or they choose to simply accept life as it is given they cannot change it.
The fact that Cherry realizes this earlier in the novel, chapter two, shows her to be far more understanding of life than Ponyboy. Ironically enough, Ponyboy does not come to begin to accept the idea that "things are rough all over" until Two-bit gives him a different perspective on what Cherry already said.
