everything, even pain. what do i do? when they start laughing like this, you can punch them and they will laugh even more. they do this with eachother and make up stories that dont make sense. they laugh if you bribe them to stop. they laugh if you pop a ballon in their face and scream at them to shut up. they laugh at everything and dont do a word you say. they are 10 and 8 years old. how do you stop this insanity?
