actually,it was..it may not seem like it but if you listen closely and know what he is trying to say then you will understand and know that it has been made for his parents divorce:(
It's about his parents. They split up. And he wants them to get back together. He now only lives with his mom so im guessing he wrote this about his dad more then to his mom. Here is a description...
The person who said that before was completely wrong the song is about his parents and their divorce. It is all about what he had to go through and what his parents had to go through.
