At the start of the film Luli can be seen drawing, using her lap for a drawing table. Another angle shows her feet moving around. If she were drawing or writing on paper in her lap she'd need to keep her feet still to avoid moving her paper.
Yeah, I heard she was born in a bar.
Luli McMullen: You could shake your knuckles at the sky. You could get mad and say I don't got nothing. You could get stuck.
