Condescension

Alright kiddo, so imagine if you were playing a game with someone who thought they were really good at it and you weren't. If that person talked to you like you were a baby or like you were stupid just because they think they're better, that's what we call condescension.

It's when someone talks down to you, makes you feel like you don't know anything or you're not good enough. It's not a nice way to treat people and we should always try to be polite and respectful to everyone, no matter what.
