In this song, we get to see what real pain and heartbreak really looks like. The singer's pain is conveyed through the lyrics in a very masterful and emotional way. Lyrics like "Pain is what happens with left over love" show that while love may be a strong emotion, but the feeling of heartbreak is even stronger. But an interesting thing to note is that the singer does not want the pain to go away for some reason. He is saying that "I'd rather feel something than be numb". This is not the kind of approach most people take towards pain, which is why I find this lyric the most intriguing.
