hates can be slowly converted to love, and love can always be generated.......

i always want to love people, and i am always trying to love everyone around me ..but.....this world is always stopping me to love because when i always find some very ugly sides from people..,,,,,,,,,,,,whenever i found them.....I halted. halted to love. and started to stop loving.......
why? why everyone has two faces,,,the face shown in front of others and the dark side that we can't know until many ages later ? LOLL
