School Sucks!

So the other day on thursday someone made a school shooter joke on me cause what i was wearing was an oversized hoodie and loose jeans. Someone said oh you look like a school shooter, don't come to school tomorrow. And cause they were my friends I went along with it, although i was uncomfortable i still did it. now fast forward to friday when i got to homeroom and then i am called to the office, i get asked to talk about what happened and i told the truth but apparently someone at the table snitched and im fuckin mad. they also said multiple people said it but then they all act nice to me. So then i get my backpack checked and go to guidance to do a threat assessment and risk assessment. I thought nothing was going to happen and now i have ISS for 5 days im currently on day 4 with 1 day left. But yesterday i finished all of my work. Like all of my work that was posted for this month. I now cant do things on my computer like watch things or play games which is dumb. I HAVE NO WORK TO DO AND THE TEACHER KNOWS THIS BUT STILL SAYS THAT I HAVE TO DO WORK. Fuck my life!
