There is another kid in my speech class (not a bad kid, just needs self control) who is a year younger than me but twice my size. Yesterday we had to do a group project, but when the subject kind of wandered out of his understanding, he just started yelling, "Fine! Fine, do whatever you want!" and just pulled out his phone. We all just kind of looked at him and told him he really should participate, and he just cussed us out and walked over to the teacher's desk. We saw him gesturing at our table but he ended up working the 'group project' by himself. I suspect ADHD or something.
