In the first line of her new song ‘Firework’  from the eponymous album , Katy Perry asks us
“Do you ever feel like a plastic bag Drifting throught the wind Wanting to start again”You may feel like a doormat used by all and uncared or maybe just like piece of shit but I doubt anyone feels like a plastic bag, that too one which is floating through the wind. Hey,lost birds drift aimlessly through the air not plastic bags. Has anyone ever seen a swarm of plastic bags going south for winter (Oh!Maybe it happens in California where Katy comes from!). The rest of the song is OK btw.
