Some say life is like a book. I’d like to say life is like a song. The same life, the same song, you can sing it sadly, you can sing it joyfully. You can sing the song of life seriously; you can sing it full of surprises and fun. You can sing it alone; you can sing it with other people. You can it as a main person; you sing it as a co-singer. How would you like to have your song of life?
