trapped in the toilet

I still have no idea how the Anti-Miley Club got a caretaker's key to the school toilets,but one day I was on my way to science class, and they shoved me in and locked it. I was trapped. I banged on the door until my fists hurt. Nobody came. I tried to open the window, but it was stucked. It dawned on me that everyone was already in class. Nobody would come to use the toilet for at least forty minutes I sat down on the floor and waited. I was friendless, lonely and miserable. Can I find a friend?
