Longing for the childhood

When I was a kid waited desperately to be a grown-up Now finally when I have come to this phase realising it is full of downs & up. Missing those peaceful nights and when everything was bright no worries of tomorrow no regrets of past just lived the life as it was with no grudges and no sorrow. There was a peace in knowing nothing then and there is a horror in knowing everything now. How badly I wish! to be that little kid again but there's no time machine I can never turn back and live that phase again.
