  Comments and Quotes  

When I was little, it never would have occurred to me to draw a picture with clouds in the sky that looked like stripes and streaks, because they didn't. How often do we see big puffy clouds now? The only kind I ever used to draw. Hardly ever. They're all spray-on. - Amber Salvati - 29
