It gives a sense of fulfillment as even though I can't be together with you but we are under the same sky so someday we may meet again and become friends keeping the last behind.
We are so caught up in studies, jobs that we do not get time to think about ourselves and someone asks how have you been and we realised that we ourselves do not know that.
The one who is looking for happiness will not be able to find it as they will keep looking for more but the one who just does what their heart says will surely find happiness.
