When you tell an unreal story, you'll have to make up one another to maintain your initial lie. Children tend to have unconditional faith in the people who they're so close to, as their world is full of simplicity and innocence. Hence, they are incapable of contributing untruthful statements to the maintenance of their idols' lies. As you grow up, unavoidably, you experience life, you become aware of different flavours of the true life. Lies, truth, tears, joy, disappointment... having been through them, eventually you will get the ability of living in the so-called adult's world. Anyway, suck it up! Keep your faith!
