Ecstasy

My friend and I went to a school dance last night. The theme was stoplight so you had to wear the color that represents your relationship status.
Green- single
Yellow- dating
Red- in a relationship
We arrived an hour late because we took forever getting ready. But, of course, on our way there she wants me to stop at the park by our school to pick "something" up. So we arrive at the park and this guy I recognize from school comes out from the shadows and hands her a tiny baggy. She hands him some money and tells me to leave. I asked if that was weed and she told me not to worry about it. Annoyed, I drive to school. As I'm pulling in to a parking a space, she looks over at me and says, "I took it!" I look over and asked her what is was. She proudly said, "Ecstasy."
I realized that this was all out of my control. I couldn't do anything about it. I couldn't believe she could be so stupid especially after I tell her not to try ecstasy at school.
I tried ignoring her and just tried to have fun, but that was impossible with her yelling in my ear, "I don't feel anything! This sucks...Let's go find Sean! I want to dance with someone...let's go over there!" After about twenty minutes of just walking around in circles and watching everyone dry hump each other, I decided I was leaving. I told Naomi that I was going and if she was going to be okay. She said yes and that she'd call me when she wanted me to pick her up. So I left.
I called Naomi when the dance ended and asked her if she wanted me to go get her. She replied, "Mandy, you left me! I don't want to talk to you. Bye." She then texted me saying she was going to pick up her car from my house later and that she was staying the night with one of her friends.
I hope she realizes that I'm done dealing with everything she puts me through.
