If someday had time machine in our world... I will go back to that moment…
When everything being perfect... And the problem can solve easily... nothing to think, just be happy everyday...
And think that it will be forever…
But the end isn’t like I’m thinking before… 
why i can't understand what this world want... everything so mysterious and hard to understand...
sometime anything that we want can't come true... but anything that we don't want come easily..
why our live can't be smoothly...
And everything can change easily... good being bad, love being hate, like being don't like, care being careless...
But if everything being smooth.. is there we will feel happy and satisfied??
A lot of question turn around in our head now.. anyone can help me to answer the question??
