What other oiling system mids were done? Need a lot more info... Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
