PLEASE don't 'show' me that I should be happy-faced or sad-faced or that you are sad-faced or happy-faced.
请不要告诉我我该高兴还是该伤心。

It is sad that Man does not wake up until faced with a disaster, but if it can be a stepping stone to a new approach it might be looked upon as at least having a beneficial outcome.
There is no doubt that everyone will encounter sad things in all his life. However, faced with sadness, different people usually take different attitudes to treat it.
