God to the picture, any how, I will ask you a question:
Some parents say let them (the children of the parents) learn by experience, if the experience is good then of course it is welcome, but what if the experience was bad and the child lost his life, will you still say let them learn by experience?
If you had a kid would you like your kid to pick the good experience or bad experience?
Rude people are those who do not thank, an example you were crossing the road and there was a car coming and you were not seeing it, then man near you shout stop and you stopped, should you say thank you or just stay silent?
