In my old school there was a new rule that you can't go to the bathroom by yourself because one girl was writing on the stalls so I went with my friend.When we went we heard the sink going on so we went to the teacher since we can't go when 2 other people are there...she said nobody else went so we went back and went in but, the moment we stepped out the toilets started flushing and the sinks were on again.We were going to take a peek and we saw the lights flickering.
