Cover art for It Wasn't Me lyrics by Jenny Lewis

the "little red wagon" part kind of reminds me of when you are little and you know, you bother your mom to let you bring this toy out and she is like "well if you want to bring it, you have to carry it". It is like jenny is going back to that time when you have to learn to be responsible for yourself, mom isn't going to pull the wagon for you anymore when you get sick of it.
