I Can't get this?

Nothings is perfect, maybe for a while but not forever Why? :) Do you ever feel that you laying perfect in the sun, But after 3 minuets you dont laying perfect any more. The roses is perfect but after 1 month they dies, The sun is up perfect warm but until the night the sunshine is gone, Nothing last forever! And you shoud keep it tight to you, and dont let it go!, Say what you want to say to the one you Love tomorrow maybe you cant any more. :)
