Biff and Happy

I get the sense that Biff and Happy are very close brothers. They seem to know a lot about each other and do a lot of things together. They do things like get a lot of girls. It's safe to say that they are players. Biff and Happy are well out of college but still seem confused as to what they want to do with their lives. Biff worked on a farm for a while far from home, while Happy stayed home working at a store. Happy even though he has a lot of potential doesn't seem very happy. They both have a lot of potential it seems like. Biff seems to be the unreliable one because he's a bit of a wanderer, not staying in one place for to long.
