Poor little pangea. This is absolutely great writing. He has taken his misfortune and turned it into a beautiful song. It relates to many of us here. We feel misunderstood and we want a second chance or give others a second chance. Look beyond what they lyrics are literally saying. Its not just that he is misunderstood but he also wants to get his life together.
"I just saw Haley's Comet she waved Said 'Why you always running in place'"
That means that other people see him as though he is running towards something but isn't really going anywhere. So he is leaving those who don't truly understand him so he can make something of himself and come back for. Wait for it. A second chance.
