First day of the second grade in highschool (nine days ago), our class was greeted with a new... not sure how it's called in english, but it's that one professor who takes care of a certain class of students. Our old one took a year off because of pregnancy.
Anyways, she talked about the subject she'll teach us, a few things about her personal life, etc. Anyways, in the middle of her speech, my phone rang (and I think I've already mentioned what my ringtone sounds like, and the phone speakera were blasting). She said, and I quote: "Usually, I wouldn't tolerate this, but this is my first day of my job, so I'll forgive it this time." I assumed that means I was allowed to answer the call. I picked up my phone, answered the call, and was greeted with my friend who called me saying he just got out of his school and is wondering what is taking me so long (he got into trouble in his school, as well, but for another reason, and that's another story). I replied I'm still in my school and will call him later, and I ended the call.
At that moment, she said to me: "Get out". I said: "I finished my call. There's no need." She said again: "Get out". I left the classroom with a weirded-out smile.
First, and (for now) the last time I ever got kicked out of a class. I did thank my friend who called me later because I got out earlier than everyone else.
