Petrello's Ten Commandments

1. I am your one true teacher of Mathematics.
2. Thou shalt remember that I am merely an archangle, and not God. Seriously, do NOT worship me, worship God instead! (Or whatever other deity you believe in, and if you think I actually am a deity, then feel free to worship me, whatever. I mean, it’s America, we have Freedom of Religion, so do whatever you want in that regard.)
3. Thou shalt recognize the Cardigan of Knowledge as the Holy Garb of Petrello. Or just “Cardigan” for short.
4. Friday is game day (And, according to Prophet Cæsar, Friday night is Taco Tuesday)
5. Thou shalt not take out your computer after taking a test until all have finished.
6. Thou shalt not erase the “loss” reference on my blackboard (And if someone already has, draw it back in there)
7. Thou shalt bring it down when you’re making a lot of noise in class or else you won’t have time to work on homework.
8. Thou shalt have your homework ready when I come around to check it.
9. Thou shalt respect my beard and my Cardigan of Knowledge. But if you really want me to shave off my beard, maybe I will, I dunno. It all depends on whether or not I feel like keeping it.
10. Thou shalt let me know if you have any questions.
