I think it's time to start trying to teach my son how to follow social norms
Can you tell me more about which social norms?
Just social norms in general that dictate the way, in which a person acts in a social setting. People claim it's what is considered normal in society.
As a parent, you have the responsibility of teaching your children how to interact properly with the world around them. Part of that includes interacting with others in society. It is a very good thing that you want to teach your son social norms as it will allow him to be a conscientious person in society and be a good friend and partner to others.
It's not for responsibility. It's all for the laughs, man.
He'll be absorbing these rules even if you're getting a laugh out of teaching him about them. I really think it's a great idea to get him prepared to function in the world.
