Page "So Yesterday" Paragraph 5

Lyrically, the song talks about someone who has got over a broken relationship, declaring the partner as " so yesterday ".

According to Duff, the song's lyrics are very empowering towards breaking up with someone and getting over it.

In a 2006 interview with Instinct, Duff said that people often told her that " So Yesterday " was " the ultimate post-breakup anthem ".

She said her mother instilled the notion of inner strength in her, and that she wanted the music she makes to be positive.

" I don't think there's very much of that out there anymore.

", she said.

She stressed the importance of strong songs that are not all about how " a boy broke your heart and you're never going to get on your feet again ", saying it was good for girls to hear.
