Cover art for Milk lyrics by Kings of Leon

yeah, I think you guys are reading way too much into this. like cardiaque said, it's about a girl he was dating in la, and what I take from it, is that the song is just a description of how she is so a-typical and magical. all of her quirks. she's late for school, she doesn't like milk, she's really sweet and wholesome (she'll loan you her toothbrush) but then she's not afraid to have fun (she'll bartend your party).
