The desperate Rat

A city rat, Ralph, sits on an alley curb.  His nose wiggles as he smells some delicious trash from the other side if the street.  He darts down the alley, staying close to the curb,  The rat loves garbage night.  He makes a break to cross the street.  Just then, a car rolls up.  He dashes to safety just through the two pair of wheels.  He has singed a bit of his fur on the hot belly of the car, but he doesn't care.  He has made it to the treasure:  3 old corn cobs and part of an old donut and part of a donut laying on the sidewalk.  He chews every morsel of the corn cob and drags the donut off beneath the rolling trash can.  A rival rat from another den appears, having sniffed out the donut on his own.  There is a brief skirmish of squealing rat.  The larger rat overwhelms him. Ralph hisses and retreats from under the can.  He skurries up the side of the can and dives into the bounty below.  Deep into his feasting, he hears a rumbling noise of clanking cans.  The light is blocked from overhead.  Outside, a vagrant has absconded with the can and she wheels the garbage to her squat beneath an overpass.  The squat is made up of shopping carts and blue plastic tarps assembled together  to form a tent.  A small boombox is tied to the child's seat area.  Dirty foam core is scattered under the tent.  As the vagrant searches through  the can, terrified Ralph climbs up and out of the tumultuous can over the back of the vagrants coat interupting her incoherent mantra. She lets out a scream and drops the pair of pants she was considering.  Ralph dashes out in the shadows to deeper in the overpass only to find the dens of a large warren of unknown rats.
