today I was in school and went to the bathroom with my friend, everything seemed normal until I had finished doing my business and started waiting for her, It did seem strange to me that she was silent but I didn't consider it important, after a while I knocked on the door of the cubicle she was in, no answer and no reaction, after a while I got tired of waiting and just headed out without her, later when we met in the corridors she asked me where I was when I said I got tired of waiting for her and headed out she said she was waiting for me, when I told her what I did and saw she just said she also waited for me and got out because I "took too long" which I did not.
this situation Is very puzzling and I would appreciate any clues anyone could give me,
