I go on coolmathgames.com and whoop little children in Math Clash to boost my ego and feel superior.
Why would you be mean like that? Are there any other sites where you like to play?
I also have fun playing chessgamesonline.com
Going on a competitive gaming website meant for kids isn't appropriate as an adult. Kids should play with similarly ranked kids otherwise they will be outmatched and lose regularly. Rather than competing against kids online and causing them emotional harm, try finding other means to boost your self-confidence through more age appropriate hobbies.
I think you don't know anything about me. Don't even comment if you think it's inappropriate for me to do stuff.
As bad things go, this doesn't seem like a terrible one. But it is a little mean to make kids feel bad to feed your own ego. You should find a game that you're just plain good at and enjoy doing well against adults.
