The wrong decision

I remember a awful story during my first year in middle school. One boy i didn't know until that year was a very rude boy to me and the teachers. He always picked on me and disrepected the teachers. One day during gym class he was trying to make a basket but accidentally tripped on his shoelace and fell on his face. Everyone including me started laughing at him. At the time I didn't realize how my actions affected him. Now two years later he doesn't talk to me nor disrespect the teachers just because of that incident. From this day on I can still remember the hurt on his face. I regret laughing at him even though he made fun of me i know i shouldn't have done the same
