Some Confusing Stuff

OKAY so some real crazy stuff went down today. Well it started this past friday, a couple of friends and I went to a takeova party up the road, so i was in the car with thing and this girl that is in my class. To skip like 20 minutes ahead after the point we couldn't find the way to the party, we finally got there and all. Had a good time but was helly heads in there. Everything basically started today, 2nd period today, one of the girls that was in the car with me driving to the party, she came in there and turned around and started saying some shit out her mouth talking about I said something about her and we go back and forth, her saying "What did I say about her, me saying " what are you talking about". We go back and forth for like 5 minutes straight. so I take out my phone and text the other people that was in the car, Me thinking is she talking about something that happen that night. so I get no answer from the people. So I am just dazed and confused, like what the fuck is she talking about. So that happen like at 10am and it's 8pm at night and I am still dazed and just clueless. So I think I will have to confront this chick and she what the hell she is talking about.
