 Avril talked about her life and what things were important to her – she was the inspiration for the song : - ) : - ) . Matthew began creating the melody and track , and I started working on the lyrics . I remember staying in bed for three days , writing 25 versions of the lyric . I love being in bed and writing lyrics , and having my dog Jet and my kitty Dash on the bed . Anyway , we finally finished the lyric , then we completed the demo .
