I had kind of a similar experience, teacher wise. My teacher knew i stammered but still pointed to me alot for answers. We had to give a presentation in the final week. I already told him 2 weeks prior that i wouldn't be giving a presentation but ill prepare the slides and everything. He can give me the minimum marks but i wont be going up on the stage. He said ok On the last week, he asked me with a chuckle everyday, u coming up or not Taimoor. And I'd just laugh it off. Then on the last day of the semester, he came in the class. Locked the room. Only 2 guys were left for presentation. And he said no one's going out till taimoor(me) gives a presentation. Everyone just started cheering me up that i should go for it but it was so on the moment that i was scared af. While the last 2 boys were giving presentations i went to the teacher but he refused. Then i went again and basically begged him to just give me 0 but i wont be going up there. After the boys finished the whole class was just staring at me and i just sat there. He then went off saying it was just a joke. No hard feeling. But i was scared and embarrassed as fuck after that class. Got humiliated and basically portrayed myself as a coward by sitting there while everyone was telling me to go up. Felt like crying afterwards but didn't want to seem even more of a pussy to my peers. That experience was very bad for me. Couldn't even complain coz i didn't actually go up on stage so no foul done in the eyes of the administration.
