life sometimes gives you a million reasons to keep smiling 
but life can give you millions of reasons to cry

because sometimes life is really painful, often giving the wound was deep. often very difficult, making such cramped and oppressed, want to cry but no power, wanted to scream but worthless. because life is sometimes very complicated to force the liver often confuse, paused for a moment and can only mourn, and when you're trying to do but not many who can appreciate it. life was really difficult to guess, sometimes there are so many things that can make you smile but then you get hurt again, give you happiness, but a few moments later just as it disappeared and no trace.
and that's life, can give you a million reasons to smile and to give you millions of reasons to cry
