<human>: I'm a 19 year old sophomore in college. I recently began giving back to the community. In one of these instances, I got a tutoring gig at a high school, where I went during the school day.  Today was my second day as a tutor. The person in charge was not going to be in the grounds today, but asked me to come in anyways.  I went to the school, but I left my wallet at home. When I arrived on school grounds I walked into the building and punched in for work. As I begin to head to the classroom of this 5,000 person school, a security guard stops me and asks for a pass. I try explaining to him that I'm not a student but actually an employee for the city/school, and that i'm a tutor. He calls me a liar and asks for my name and class to verify. I told him the class I was going to, but the teacher was not present  and there was no class at the time(I got there early). This lead the security guard to think I was lying. I tried to explain to him I worked for the city, but he thought I was skipping and trying to be a cheeky little smart-ass. He called the cops over and had them escort me to ISS(In School Suspension). Cops tried to get my name, but I was not in the system (not a student there, or at any high school) and they thought I was either from some other school or just lying to them. I didn't want to get in any trouble, but I was being honest. They kept me in this room for 3 hours. After the three hours, I managed to get in contact with a sub that had received the class instructions, which had my name listed as a tutor. At that point my tutoring session was over, the cops and security guards brushed it off as a funny story. I was not amused. I left the school, being warned that I should get a proper badge/ID (which you don't get unless you are full time staff). I was pissed, but I did manage to make $40 for being suspended. Teacher found out and sent me this really apologetic email when she found out, which was a really nice.

<bot>: 17 again isn't as cool irl as it is in the movies. And I was that senior poser from boyhood.
