You go and buy a delicious looking cake and then go to your home and try to eat only to know that it is not properly cooked from inside.
Life is also filled up with similar people. They look very nice, humble and hardworking from outside. And yes, these people have really experienced the hardship of life but ironically, they have missed something during those hard experience. The have lost their ability to be graceful and respect other people.
They are like the half baked cakes; you cannot eat yet you feel uneasy to throw out.
