There is a special bathroom, not a water room. A two-story building, one for boys and two for girls. The bathroom is quite spacious, with partitions between adjacent rooms. Simply put, you have seen the toilet, which is the effect of missing a door in front. It is impossible to be completely undetected. If you really mind, don't go at the peak time like night, at noon or afternoon. . . . You can find a deserted place nearby. . . . But then again, don't be too nervous. Everyone is going to take a shower, not to go to the movies, it's foggy inside. Who's watching? . . . .
