Dad, I Miss You! How Are You in Heaven?

I always thought that the future would be long, but I never thought that "the tree wants to be quiet but the wind doesn't stop, the child wants to be raised but the kiss doesn't wait." Dad, your sudden departure has left me with no chance to fulfill my filial piety. It has left a lifetime of regrets for which I cannot forgive myself. Dad, I miss you! Thinking of you every day! But I can no longer find your footprints. Dad, how should I spend the lost days for the rest of my life? Dad, you will sleep forever and I will remember you often. How are you in heaven? I wish you in another dimension can live a long and smooth life without disaster or disease!
