Cover art for Smoke lyrics by Natalie Imbruglia

seriously this is such a good song, yeah one of her best. It seems to be about physical/emotional abuse: "Why, Bleeding is breathing", "Why, Bleeding is believing". I think it means: do you really need to bleed to know you are alive? Like is that the way to live, with her father hitting her and her mom 'hiding underneath the smoke.
