When things had become sour or it didn't turn out as what you wish for...I think it is no point of saying anything.
No matter how much you want things to become better or you thought it will be better if you were in charge. We have no power to predict the future.As a Muslim we have to believe Allah Almighty created all things including Fate. We can only pray for the best because only Allah knows what is the best for us. Salam Maal Hijrah.
