Cover art for My Best lyrics by Vanessa Carlton

I always thought tht the song was about friends that end up dating, but that it did'nt work, they fighted, they broken up and he's left to somewhere. But after all they were still friends, and they never give up of the friendship, like they had promise always give their best to weach other, and they still keep touch besides he's away.
