There are many reasons, I'm sure all of which can be traced back, way back-- if one liked to do that sort of thing. Personally, I don't. I prefer to love shimmering plastic, in all it's shimmeringness.
Many people have told me it's an irrational thing to do, to love plastic. I tell them their fools. I don't love plastic. I love SHIMMERING plastic. Then they leave. I don't mind, it was time for them to go anyhow.
Lastly, I'm not ashamed of my lust for plastic that shimmers. I just get angry when people think I said 'simmering' plastic, and they've gone out and bought a vat of hot plastic for me. According to etiquette, I have to thank them and accept the hot plastic. But it's hot, so I don't, because I like SHIMMERING plastic. Why can't they understand.
