Today, Roan got 'in trouble' or rather a stern talking to about not thinking of the consequences of his actions and how his not thinking about things ruins MY stuff. I tried to explain to him about common sense and how it's important for him to learn what common sense is. His exasperated response to me through his tears, while trying to get me to appreciate that he just 'didn't know', was, "Jeez mom! I'm not Stephen Hawkings." My anger dissipated at this point and the conversation was over. I had to walk away to hide my smile.
I figure if he's smart enough to throw that sentence out at me, then he should be able to figure out what actions will piss me off.
