Isn't it dump

So... I was at school (high school) and I was in class. Since, I forgot to call my grandma, for a pick up. I was stressed about it, because I knew I had an appointment at the last period. So, I asked my teatcher if I could call her. He said yes, in the hallway. I didn't hear that it was in the hallway, so I called her in class. AND I GOT FIRED BY HIM BECAUSE I HAD MY CELLPHONE IN CLASS. Like what the hell, this is so unfair... I asked for it, and even if I didn't understand that it was okay in the hallway, he want to take my phone... GOD DANM HELL, HE IS SO STUPID.
