It's true what our parents and elders tell us when we're younger.
"Don't wish your life away."
"Don't grow up too fast."
"Enjoy it while it lasts."
Youth is impervious to this wisdom.
It's ironic that the young can't wait to get older, as if it brings some true autonomy and relevance, and the "grown ups" yearn to be young as if youth is the only time life is really pure.
