Unwarranted Death Stare

So I'm walking down the hall, minding my own business, trying to get to my period 10/11 Creative Writing class on time and in front of me is a nice little girl that sits in the back right corner of the aforementioned class, and she's walking along with another nice little girl from the class, and Nice Girl #1  happens to turn around and she's sees me and makes eye contact and gives me the meanest glare imaginable-- a death stare-- and then she turns back around and walks into the class and I follow her and when I get into the room, I say to her "What was that for?" and she says, "I'm sorry, I predicted that you were absent because I didn't see you when I walked by class, so I told my friend you weren't here and then when I saw you in the hall I got really mad that my prediction was wrong."
