Analysis Of Annalise's P. O. V. Slam?

Annalise's P.O.V:
SLAM!
The door slammed in my face by that stupid fucking math teacher, like who does she think she is. I was late literally two minutes. Apparently going to the bathroom is a motherfucking crime. This was the fifth time she sent me out...this week. I wait for Mr.Mike to come do the usual routine, shout, joke around and then give me detention.

All of a sudden I hear the familiar slam and I see Xander, my best friend of four years, coming towards me so I ask,"what did you do now, you idiot?" "First of all, fuck you, you got sent out first, secondly I fell asleep again." I chuckled, he always sleeps in the last two periods. "So what do we do know?" I asked. He suggested we skip cause he wanted to tell me something and he sounded
Xander and I were sitting in the middle of the football field. We were waiting for his mom to pick us up because I had gymnastics practice after school and none of my parents could pick me up at four. I was lying on the grass facing the sky. "Annalise, can I trust you, like you know with my secrets and stuff?" I faced him. "Yes, of course, you can. What brought this on?" "I don't know , but I want to make a pact to make our pact official, you know?" Now I fully faced him. "Ok, how do you want to do this" Then he pulled a piece of paper out of his pocket and started reciting," I Xander William King, swear to keep no secrets and confessions from Annalise Winter Valentine, my now official best friend. Annalise, it's your turn." So I followed. "I Annalise Winter Valentine, swear to keep no secrets and confessions from Xander William King, my now official best friend." He looked at me with such intensity while I said my part of the oath. It looked like he was looking for any reason to suspect if I was lying or not, I wasn't. When he was sure I wasn't lying, he suddenly leaped on my and gave me a huge bear hug.

I laughed at that, I always go to la la la land, But I stopped when saw him he looked really serious. He sighed, ok I was really worried now. "Xander, what's wrong, you're never this serious. Ever." "Lisa don't get made until you hear the entire thing alright?" I nodded signaling him to continue. "Iamdatinggisele!" "What, say that again please?" "I. Am. Dating. Gisele."
Wait...what the fuck!! I felt a sting in my heart but I that wasn't important right now, right now I was pissed. "And when the fuck sake were you going to tell me huh!! That you and Gisele were together. And for how long exactly?" Gisele was also my best friend but for eight years. How could they keep this from me? I trusted them both especially Xander, with the pact and all. What he said next practically shattered me. " Four months."

I couldn't hear the rest, so I got up and went running down the stairs almost breaking my neck twice, and i suddenly saw Mr. Mike at the end of the staircase. He was pointing at me to come
