week 24: Mrs Hudson in the English room with a purple pen

Mrs Hudson's pen was just with her, and then the next second it was gone. I know who took the pen, But I dont know if I should rat them out or not? Should I be a good friend and just go along with it? will they get mad if I tell? Everyone thinks I stole it and the person that has the pen isn't even trying to blame it on someone else so I dont get in trouble. I went into the next room to tell Mrs Hudson that Taylor stole the pen. After I told her, she went into her room and walked up to Taylor and asked for her pen, but Taylor didn't have it anymore. she passed it on to someone else. Taylor was hiding it in her left pocket of her jacket. I dont know who she passed it on to, but maddy is looking guilty now. I think she gave it to Madison. I told Mrs Hudson one more time who I think has the pen. She asked and Madison and she just stood there laughing. After everyone else in the class saw that Madison was the one with the purple pen they realized that I didn't have it and got mad at Madison and not me.
