Context: It goes out , and the far corner of the lot settles into the regular darkness . The back seat of the car is cluttered with blankets and shoes and tents , a purse he ca n't figure out the owner of , and a box of napkins that 's still full but ripped apart , crushed under the weight of all the junk . Ivy has draped herself over the pile of junk , and stares out the window of the car , drawing aimless lines into the dust and she wonders how he can see out of the window , with the patina of grease and dust and the milky tint of age that 's crept into the glass . " Why have n't you ever washed this thing ? " " I do n't see the point .
