what is dallas' problem? why do you think he annoys others?

"The real character of the gang," Dally was arrested his first time at the age of ten. He spent three years on the "wild side" of New York and likes to blow off steam in gang fights. He is the most dangerous member of the bunch—not even Darry wants to tangle with him—but he is still a part of their greaser "family." Dally likes to push people and situations to be noticed. This is the only way he knows how to express himself. Agitating people is how he relates to them.
