Lyric discussion by evalente 

I like the concept that "the only rule is, it begins" can apply to friendships. Friends carry all sorts of roles, and these roles strengthen and weaken, materialize and vanish, through the years. You could fall out with a friend for years, but there is no rule that "it's over". The only rule is that it began, and where it goes from there is the story.

@evalente I agree. Before I learned the real meaning (thx @taylor720), I imagined the song was about friendships/relationships. They begin and then it's up to the two individuals in them to maintain it (i.e. the friendship/relationship) and determine "how long it goes" and "what they contain." I don't think the same parallel can be drawn with life, as you can't really control "how long it goes." I honestly never really cared for this song, but then I heard Trey play it solo acoustic a few times and the lyrics grew on me....
