This friend, we’ll call Alex, and I have always playfully made fun of each other. I’d call her ugly, she’d call me an idiot. We never did anything that would offend the other.
Later, we start debating about the technical definition of a stereotype. Our debates have never had a conclusive ending to them before, but for once, we finished. I won the argument, and she was speechless. I laughed it off and thought it was the end of it.
A little while later, I’m on my way to the trash can to finish up my water bottle and to throw it away. As I’m drinking it, she lifts the bottle so that it spills on me. I turn around, and try to spill the water on her. I completely miss. She laughs at me for missing. I wait until she’s behind me to do it again, and the bottle hits her in the face.
This infuriates Alex. She grabs me and doesn’t let go. She says she’s going to give me a swirly repeatedly. I try to push her off me and I keep trying to run away, but she drags me out of the cafeteria into the bathroom. I keep pushing away and trying to run, and she keeps pulling me against my will.
At this point, I have gotten out of her grip enough to where she is only holding onto my sweater. I rip the sweater off of me and sprint away while she tries to get the stall open. I left the sweater in her hand. When I get to my locker later in the day, my sweater is in there, soaking wet. She had soaked it in the bathroom.
She sarcastically apologized, and I unexpectedly started crying. I reported it to administration, and she screamed in face about being overdramatic. I personally believe that what I did was perfectly acceptable for the situation. I’m still shaken up from what happened, but I need an objective perspective.

AITA for reporting her?
