I made a kid cry in school and I've never told anyone

I was 10, he was 6 or 7. I had just gotten my first pair of contact lenses and was very proud of myself, and I thought I was doing everything right. I was wearing my contacts at school. I had gotten instructions from the doctor on how to put them in and take them out and everything. I sat in the back of the classroom with my head down, trying to get used to the feel of having contact lenses. After a while, I figured they were in and decided to go back to work. The teacher had given me a notebook to write in, but I could still feel the contacts in my eyes and couldn't see a thing. So I did what any self respecting, 10 year old would do. I drew penises everywhere. I drew them as the answers to our math problems, I drew them in the boxes on our word searches, everywhere. The kid next to me was busy doing his work, and after a while I noticed him staring at me. He had finished his work and was staring at the notebook I was using. Every single place I had written something, there was a huge penis drawn. He asked me what the hell I was doing, I laughed it off and he started to cry. He said that I was disgusting, and that I should go to hell, and he asked if I drew those in front of me. I stopped laughing, and told him to shut up, and he just cried louder, and told his teacher. I was sent to the principals office for being uncooperative and disrespectful, and the kid who had cried got a trip to the principals office for being uncooperative and disrespectful too, because he wouldn't stop crying. The principal asked me why I had drawn penises everywhere, I told him I didn't like that kid, and he told me to go home. I never told anyone about the contacts, and that's the only time I ever drew penises anywhere.
