Exposing Teachers

So, last week we were in class ofc. We were just talking like normal people- And then this teacher, we will call her Mrs.D cuz I respect her privacy. But I will call her Mrs. Denomic sometimes. This teacher had the actual audacity to scream and shout "BE QUIET" And then this pac man built ahh person got me suspended for 2 days cuz they said i threw the finger sign. Like wtf-
