How would you describe the relationships among the Greasers?

The Greasers are like family.... brothers.

Or I could have gotten one of the gang to come along, one of the four boys Darry and Soda and I have grown up with and consider family. We're almost as close as brothers; when you grow up in a tight-knit neighborhood like ours you get to know each other real well.

The doctor told us that he would talk only to the family, but Darry finally got it through the guy's head that we were about as much family as Dally and Johnny had.
