"there was once a girl who was very bad tempered... and her mother was very unhappy about it... So she told her..every time u wanted to vent your anger... go to the fence behind our house and knock a nail into it... and so the girl knocked many many nails into the gate but one day.. the girl changed... and this time.. her mother told her... now when u curb your anger once and didn't show your temper.. u can pull out a nail from the gate... and so... after some time.. the girl managed to pull out all the 37 nails from the gate "and so the moral of the story is... no matter how u remove all the nails... the holes will still be there... old wounds doesn't heal that easily..
