Some people are very sensitive and get hurt easily by arrogant and rude behavior of any one who know them. They try to make every one happy but some times extra kindness and sweetness may harm us. I know it sounds so weird but it is the reality of today's world as every one is greedy and think about their benefits and some people run very fast in this race so that they even don't care about the emotions of those who really cares of them and support them just for kindness. Success is good and important but if it hurts other and make you wild then it becomes cancer which later on becomes chronic if it doesn't treated. I can end up my words by saying that:
People of early centuries were so innocent as they make relationship without any greed.
Then people became clever first they saw benefit then made relations.
But know people becomes practical if they have benefit then they make relation otherwise they break it.
