Sophomore Year: My "friend"

So i had Math first period and i didnt really know anyone in that class. The only peraon i really knew a as a friend of a friend so i would usually sit and chat with her and sometimes help her out with math. One day she was called to the principals office and before she left she looked at me and said " if the police officer comes downnto het my stuff i have a knife in my frint pocket and i want you to hide it for me" and walked away. I then started to freak out becuase why dose she got a knife on hed at school and why did she tell me about it. Eventually she came strolling back into the room sucking on a sucker and just looks at me and smiles. She then thanked me and just went on with class. A little while later she said " i have a knife because i deal weed and i dont want people stealing my stuff and i gotta protect myself so i keep a weapon on me". She then said "i thanked you because i knew that ifnit came down to it ypu wouldbenhide that knife for me". Honestly i dont thinkni wouldve hid the knife thobecause j didnt wanna get caught up in it. A couple days later i was pulled out of class by the principal because they had a tip that a student had a weapon on school property and that i knew who the student was and if she actually had a weapon. i told her that so.eone told me they had a knife in thwir backpack butbi never actually seenit so i wasnt surenif she actually had one. The principal then thanked me for being honest and sent me back to class. Then when i ran into the stidenr i told her what happened and she said she wasnt upset said she understood why i told andbsaid she knew who told on her and said we werw still friends.
