A strange look at me....

I had my teacher from University coming to observe my class today. I decided to tell him about last week class with him and to complain about students in his class eating during lecture.

I think I felt right prat! He was amazed that I could hear these noises. He said am I supposed be deaf?
I explained to him that Cochlear Implant is much more powerful than hearing aid and receive a lot more frequencies than hearing aid can get, but it is up to my brain to try translate what the sounds meant, thats why I cannot yet translate speech and continue need interpreter for group conversation and classroom.
He said he will talk to the class and ask them to restrain from eating during lecture
