It all started 3 years ago during when the chicken and her friend rooster were out shopping for a nice new PSP. they were strolling along wing in wing as all newly weds do, when the rooster spotted a good deal in a window across the street, "PSP ONLY $120". Quickly he dashed across the road towards the shop, leaving the chicken on the other side. As the rooster was halfway across the road, a large truck swooped in and hit the rooster, launching him into the sky team rocket style.
Since that day, the chicken has never crossed the road, and as luk would have it it was a ring road surrounding the city, so the chicken never left the city after that moment... until today, the chicken was walking peacefully along the road where only 3 years ago her husband was tragically taken away from her. Just then she noticed a rooster standing on top of a building, thinking it only to be a weather vane, she thought nothing of it at first, but on a second glance, she saw it was her rooster, suddenly without thinking she ran across the road...
Thats the only reasonable reason for a chicken to cross a road... why the hell else would it be out of the coop...?
