Don't let people write on you!

I encounter a lot of funny and random things in my life. This is just a minor example. I believe that it classifies as both funny and weird.
So, I was sitting in my Spanish I class on Friday. The teacher was gone and we had the usual busy work packet. I got to work and was making good progress. Suddenly, I heard muffled grunting and the sound of a chair being moved awkwardly back and forth across the floor behind me. I know that some people have problems with Spanish, but this was a bit much. I turned around and asked the dude what his problem was. He said he needed a pen. I gave him my pen in the hope that the caveman like noises would stop. I thought that if the guy was upset enough to grunt and scoot his chair around on the floor then he could certainly borrow my pen. At the time, I thought that the guy might have some kind of mental problem. I felt sorry for him. I hoped that my pen would help to calm his neurotic anxiety. I had just turned around and resumed my work when the grunting and scooting resumed. I turned around to see the grunting chair scooter awkwardly trying to mark something on his arm. He was having a really hard time. I asked him what his problem was, and then he showed it to me. It was one of the most embarrassing things that I have ever seen. Someone had drawn a very obvious penis on the back of the guy's arm. He could not reach it to mark it out. Who ever did it must have been very cunning. I applaud their ability to draw a penis on someone where they can't reach it. I also congratulate them on drawing it in an easily visible spot. I offered to help. I started to scratch out the penis. I was about halfway done when he yelped slightly and swatted me away. His face looked like I had been branding him with a hot iron. He said that he couldn't stand it anymore. I didn't know a Pilot G2 was that torturous. Apparently, it was to him. As far as I know, he spent the rest of the day with two large and visible balls on the back of his arm. I end my story with one of my rules to live by. Don't let people draw things on you, especially penises.
