just talk to him if you need help with a grade .
Mr. Harrison is one of my favorite teachers of all time. (:
Harrison is THE MAN. Period. Great teacher. Great guy. If you have a chance to interact with him, DO IT. You won't regret it.
Everyone loves Mr. Harrison. It's a law. Had a good time in World Civ, and he still remembers me. Cool dude, cool teacher.
