My classmates can not chill

In gym, I was playing with a big red ball, till two of my classmates decide to gang up on me and try to steal the ball away. After that, it kept happening, I kept falling and scraping my knees, and more kids kept trying to steal the ball and the teacher somehow didnt see what was going on. So I had got ganged up on...and it was most of my classmates against me ;(
