God answer: "TIME" my child...
But why TIME and not LOVE?
LOVE you can give that, you can have that, you can share that to anybody...
But with time...you can't stop it or control it cause you can never bring
back the time that has passed by...
So spend your TIME wisely & cherish
it with your loved ones!...
Cause you'll never know when your time or their time is OVER...
Take care my dear friend ...
May God bless & keep you always!
