[Jackie] started asking what I said, thinking maybe it was something about her. It wasn't about her, but I still didn't want to tell her. I told her it wasn't about her, but she still wanted to know.
I told her maybe I just like [Jill] more than you. [Jackie] didn't like that. She said, "fine," and got up and left.
[Jill] asked why I would like her more. She said me and her never even hang out with each other. She also left.
Later that day, I tried to apologize [Jackie]. She didn't say anything. I kept trying, but she gave me the cold shoulder for the rest of the day.
After school, I got home, and [Jackie] called me. She said, "I can't believe you told [Jill] you failed that math test, but you didn't tell me. You know she doesn't even like you that much. I would've at least supported you instead telling a bunch of other people."
I was surprised [Jill] told a bunch of other people, but then I realized [Jackie] was right. [Jill] has a bunch of "cooler" friends than me. She would just go and tell all of them.
I told [Jackie] I messed up, and it won't happen again. She said, "It's okay, just remember that I'm always gonna be a real friend."
