Sometimes you are afraid of something and consider it a disaster, and you even may have some nightmares imagining it happening to you. You think if it happens then it's the end.The surprise is when it really happens, and you figure out that all your negative thoughts were completely wrong, and it's just a gift from almighty God
So many times I realize how false we are when predicting future. Future is a real mystery and trying to predict it is useless and exhaustive - so as the past of course.
