I put my shirt in my mouth and then told my wife she was rude for slapping my hand and shirt away from my mouth.
Why did you want to do something like that?
I think it's funny to do silly things like put my shirt in my mouth.
While it's good to be silly sometimes, there should be a limit to where it can be obnoxious. Your wife is right for trying to stop you from doing such juvenile things, you are and adult and should act like it.
What are you implying?
If you are behaving in an unbecoming way it would be expected for a spouse to correct you.
