I caught one of the people I considered a friend of mine, badmouthing me and my group of friends. Confessed that a long time she would manipulate me to get good marks and my lab reports even if I refused. To make her angrier I continued acting nicely but every time she would ask me something I would invent an excuse to go away from her. Every time she would approach me, I would talk to my group of friends making a wall between me and her gradually. So time passed and the end of the semester came, by the group of the course we were in, days later came the list of the people who needed winter courses to pass a certain subject because they failed the final exam before doing the papers to enter to specialty. I saw the list out of curiosity, and to my surprise that toxic manipulative person had failed physiology. Karma sweetly played for me.
