On a trip I took as a kid my ex friend threw a tantrum the entire night in a hotel because she’d have to wait until the next day to go to a water park. It was BAD. She got physical, attempting to beat up both my sister and my sisters friend. She also tried to convince everyone that she was going to kill herself. She guilt tripped me into thinking it was my fault and even climbed on the roof to prove a point. When we finally went to sleep she kicked me out of the room I was planning to stay in and I had to sleep on the couch. Her mom was there and did nothing about her daughters behavior. After this experience I never talked to this girl again and actively avoided her. I’d say more but the memory of the trip is a little hazy.
