Discrimination in my words is separating people from other people because of what they look like or what they sound like. Being different in jeneral. Discrimination still happens a lot today in our society but just in different ways. People might be discriminated because of a disability or because they way that they talk.
I have witnessed people have to go through discrimination. This kid wanted to play soccer with some kids but they didn't let him play because he wasn't the best at the game. The kid was really sad and he started crying because he really wanted to play but they wouldn't let him.
