My kids went to an international school outside Japan . They were badly unprepared for the Japanese curriculum . There is a reason Japan is consistently one of the top rated nations in terms of education . And they adapted , learned , had some rough years , and are going to public elementary , middle , and high school . <| sep |> I used to work in a correctional facility . Many stories come to mind , but two really stick out from the rest . I was sitting on one of the booths outside the dorm cells . Suddenly , a loud terrifying scream of pain and agony ran out of the cell dorm wall through the hall and out to the recreational area . If I could describe the horrible cry it would be as if someone that had just been killed or died in an accident and could not believe heshe was dead . Every hair on my body stood up . I went inside the dorm where I thought the scream came out of . Everyone was asleep except one of the inmates . I asked him who screamed ? I could see the inmate was pale white with fear , then he said that no one did . I asked him then what happened ? He the pointed to the wall next to him and said , it came through here and went that way . He pointed towards the area where I heard the scream pass through outside of the dorm . There was a hallway located right before you got to the post dividing door . This hallway had 3 doors on each side . One side was the medical room door , the attorney visit door and the other to the recreation area . The other side doors were to the lobby , visitation room and to the front offices . Every time you passed through there at night something would knock on one of the doors . You never knew which door was going to be knocked on . Again during the midnight shift no one should be on the other side of the doors . One night around 4 am I passed this section and to my surprise there was no knock . I turned around towards the doors and asked , what happened you didn ' t knock ? Immediately after my challenging question it started knocking on one of the doors fast and loud . I nearly shit my pants and that dividing door could not open fast enough so I could get out of there .
