We had great time in Hokkaido, also very tired. On the way, I made a blunder. We lost sight of my son. We got on a train from station to station during 1 hour 40 minutes. When we got off the train, I noticed that he absent. The blood drained from my face. We were all afraid for his safety. I was worrying until be caught in took the first station. It's nice that my son all right and I'm relieved. I deeply regret myself.
