How do teachers feel about students that...?

How do teachers feel about students that don't need to pay that much attention in cl to get an A. Not to brag or anything, but I'm in this AP cl and I constantly talk like no other to my friends. I barely pay attention and the teacher always tells me to be quiet, but in a joking way. Anyway, I'm still getting an A, while other students have to pay attention and struggle to get an A. How do you teacher feel about that? What if you had a student who was like me? Would you intentially try to lower his grade or would you be astounded?
