Thats life..

No matter how hard we fight & quarrel with our parents....even when you decide never to talk with them and to run out of home...

But when after sometime your father or mother comes to you smiling.. sits near and gives you that look he/she used to give you when you were that little quarrelling naughty child, 

You just forget everything that you decided.. 

and both of you start laughing and you run into their lap hiding your face crying, it never does matter 

how old you are, however rich, however high your social positions may be...

Thats life..
