and you look out the square window , back over the road you drove up on , and you look at the hills and the mountains all around you , going pink as the sun goes down and the air gets cold and your legs get cramped hunched down , and every so often you reach down by your feet and pick up the canteen and take a swig of the warm water inside , tasting the purification tablets you dropped in there this morning and feeling cold come up through your feet and into your legs .
