The star festival

We have the star festival as an annual event in Japan.
According to Chinese legend,a god separated a pair of stars that were lovers. Since the Weaver (Orihime) was so lovesick for the Cowherd (Hikoboshi), she did not do her work, and the got put the Milky Way between them.
After that, they can see each other only on the night of July 7th. So, the day is celebrated as the star festival, based on the legend.
People write their wishes on strips of colored paper, and hang them on the branches of leafy bamboo and put them outside at night.
So, of course, I wrote my wishes on a piece of paper and hang it.
By the way, my brother, Hirotaka, said a sad story. I was very surprised at his story.
He said that it will take 15 light-years to get to the Milky Way from the Earth. So, my wish will reach the Milky Way when I am 35 years old. And then, he added that the answer from there will come back when I am 50 years old. He adviced me that I should write wishes for myself after 30 years later.
