The following is a today's talking with my son before I sent him to the kindergarten.

my son:"Dad, I don't want to go to the kindergarten"
me:"No, you are a kid. Only you go to the kindergarten can you grow up"
my son:"I havd already grow up. I want to become mam"
me:"Why do you think so?"
my son:"I want to go to work and earn money"
me:"What would you like to do when you have money?"
my son:"I want to buy some toys for dad"
me:"oh, my good son!!!"
