Not to be a smartbutt but the word you seek is principle. "Principal" is the dude you don't want to be sent to in school.
Serb,
I'm sorry.
You are correct.
I did not look over my reply before I posted it.
Thanks for pointing out my error, and I didn't take it as you being a "smartbutt".
Thanks again......
Im waiting for q_q_ to say something about the typo. It is fascinating that todays youths do not concentrate on spelling skills, nor grammar. It seems that in the Internet age the skills which were important in written communication are no longer taught or they are not learned. I must be lucky because my mother was an english teacher in elementary school and instilled in me the importance of spelling and grammar.
It is also very easy to spell correctly in the Internet age due to the simple technology of spell checkers. Even as I type this reply my spell checker has corrected several simple typing mistakes I have made. I recommend that everyone who uses Firefox should take advantage of the spelling checker and when there is a dashed-underline under a word, just right click on the word and the pop-up menu suggests the correct spelling.
In this particular case the spell checker would not have corrected Principal because Principal and Principle are homophones (

I would have used the word Smartypants instead of Smartbutt, but that is your decision.
