Today when I came back from football training I was sweating buckets and decided to take a swim for just half an hour. As I was swimming I heard a boy say to his friend "dude you're so retarded, you can't even break this level?" I looked and saw the boy. He looked like he was in 5th grade. I knew the boy was using the term 'retarded' in a negative way, and that wasn't being nice to his friend. So I just told him that we shouldn't use those words but he just ignored me and walked away. I felt guilty for using inappropriate language a lot then without knowing the meanings. I also felt that children learn a lot from us, our society and the internet.
