I went out going by train with my wife and son on Sat.
Until before we came back, we enjoyed and have a good time
but when we were coming home, my son had losed energy more and more. Soon he fell asleep, leaning on me on the train. I though that he is just tired but 
even after we got home, his energy didn't come back.
Then, I doubted that he is sick and he already have a high fever that's why we go immidiately to the hospital and the doctor said he had hand-foot-and-mouth disease,
