- / things that exist or are used or enjoyed for only a short time./
Time has proved that the look of human is the most changeable thing. Youth and Beauty only exist in a certain time of our lives. Vivid and grand as they may look, they are vulnerable and light; easy to feel but hard to hold.
Once within their grasp, human must make the most of those moments. They play and fly high with them, for the fear that the wind might come and blow them away forever.
