Soo funny :) soh cah toa!! :) he even did the sword actions! I will never forget that lesson!!
Give Mr Derby a break! Taught me on Justin Craig, he's not half as bad as you guys think he is. Just take the time to listen to him!
He is a nice teacher, and if you listen to what he says then you will understand. the problem in class is that people do not listen and so they don't give him a chance to explain!
