There was a case with me when I was a child when I was locked in the toilet. The handle on the door of our bathroom was round with a button in the middle – this button and closed the door to the lock. I went to the toilet and closing the door, as usual, pressed a button. Maybe I knocked too hard or something broke inside, but the pen remained in my hand! On the other hand, the pen fell off: I heard it fall on the floor. And here, I stand in the toilet, the door is locked to the lock, and I don’t know how to open it. Mom and Dad are at work and will come only in the evening, I am home alone. Crying is useless - it is unlikely that the neighbors will hear me, and the situation is unpleasant, but not critical. So I stayed locked up in a small room until the evening, until my father came and released me. After that incident, he rained for a long time and nodded over me.
