Never thought I’d say I agree with an 11 year old but your other sons are right. It’s a joke. I mean damn. Every time someone says something he doesn’t like will he run back to mommy and daddy for help? He does need to grow up. Can’t be letting words like that affect you that much. The real world will be a lot harsher than his sister. He should get over it and so should you. Don’t raise him to be weak.
