Deri is my favorite teacher. His class is fun and engaging, and he has a good sense of humor. He is able to present challenging material and make learning fun. My favorite part about Deri is that he is extremely helpful and forgiving, but he is NOT an easy teacher. Deri will push you to do your best. Overall, Deri is a great teacher and knows what he's talking about.
Dude, Deri's the man. I'm tired of all this Deri-hate.
Deri "right-clicking" Bash, what more can you really say?
