if i was an astronaut, i would have flown to the moon and got used to the blue sky hottest star! i flew to the universe would rise to the sun is high, and took a bit of individual rays, to carry only all good. i would have rounded our earth, travels to the poles, the tundra is met b bears white and the starry-eyed penguins. i'd studied the atmosphere, to lay down on the clouds, caught right on venus would have met the aliens. i have reviewed the entire jupiter all of the constellation used instantly counted, and would fall directly on the palm of your hand i'm brilliant meteor. i'd grabbed the tail of a comet, and she would have suffered me the expanses of space, erasing all of a second of daylight. in the solar system inadvertently i will land right on neptune and i see in the distant cosmos bright north star. suddenly, standing in orbit i will order the comet, "wait! " and when the silvery moonlight i'll admire the moon suddenly, she suddenly dissolved, turned into a black hole fly burning comet, putting out the north star. the sun bright flash at parting, the bright beam waving after me, and, like a dream, my suit away, dissolved in a sweet dream, the moon but in the left hand, will burn down, that star fallen from heaven the fragile miracle of cosmic i will leave in the heart forever. do not embrace our cosmos in minutes over the years he did not learn but while there is the world's astronauts, on our planet worth living!
